Peter Killian Gallagher was born on August 19, 1955, in New York City and grew up in Armonk, New York. His mother, Mary Ann, was a bacteriologist, while his father, Thomas Francis Gallagher Jr., was an advertising executive. Gallagher attended Tufts University in Massachusetts, where he became involved in theater and music. While at Tufts, Gallagher performed with the university's a cappella group, the Beelzebubs, an organization that would later become well known far beyond the campus. He also appeared in theatrical productions and quickly discovered that performing offered considerably more appeal than pursuing a conventional career. After college, Gallagher began working professionally on the stage. His Broadway debut came in the 1977 revival of Hair, placing him immediately inside one of musical theater's most famous productions. It was the beginning of a long relationship with the New York stage that would continue alongside his film and television work. His early Broadway career included the original production of Grease and, more significantly, the 1982 revival of A Doll's Life, for which Gallagher received a Theatre World Award. He later appeared in productions including The Real Thing, Long Day's Journey Into Night, The Corn Is Green, Guys and Dolls and On the Twentieth Century. Gallagher's movie career began developing during the early 1980s. One of his first significant film roles came in The Idolmaker in 1980, directed by Taylor Hackford. During the decade he continued appearing in movies while maintaining his stage career, gradually becoming one of those actors audiences recognized even before they necessarily remembered his name. That changed considerably with Steven Soderbergh's 1989 independent drama sex, lies, and videotape. Gallagher played John Mullany, a successful but deeply flawed lawyer whose marriage and infidelity are exposed through the arrival of an old college friend played by James Spader. The film also starred Andie MacDowell and Laura San Giacomo. sex, lies, and videotape became an enormously influential independent film, winning the Palme d'Or at the Cannes Film Festival and helping establish Soderbergh as a major filmmaker. Gallagher's performance gave him increased visibility and opened the door to a busy period of film work. He appeared in Tune in Tomorrow in 1990 and then joined the cast of Robert Altman's acclaimed 1992 Hollywood satire The Player. Gallagher played studio executive Larry Levy alongside Tim Robbins in a film populated by an extraordinary number of recognizable actors and celebrity cameos. In 1993, Gallagher appeared as Buddy Kane in Robert Altman's Short Cuts, another large ensemble drama. His work with Altman helped reinforce Gallagher's reputation as a dependable character actor who could hold his own in casts crowded with major performers. Then came a romantic comedy involving Sandra Bullock, mistaken identity and an inconvenient coma. In 1995, Gallagher played Peter Callaghan in While You Were Sleeping. Bullock starred as Lucy Moderatz, a lonely Chicago Transit Authority employee who secretly admires Peter, a handsome commuter she sees regularly but has never actually met. After Lucy saves Peter following an accident, he ends up unconscious in the hospital. A misunderstanding leads Peter's family to believe Lucy is his fiancée. Rather than immediately correcting them—as any sensible person would do and thereby end the movie after approximately 14 minutes—Lucy becomes increasingly involved with the Callaghan family. Complicating matters further, she begins falling in love with Peter's brother Jack, played by Bill Pullman. Gallagher therefore spent a surprisingly large portion of one of his best-known movies unconscious. This is either unfortunate or one of the easiest leading-man assignments in Hollywood history, depending upon how comfortable the hospital bed was. While You Were Sleeping became a major box-office success and remains one of the most popular romantic comedies of the 1990s. Although Gallagher's Peter was technically the man Lucy initially dreamed about marrying, Bill Pullman's Jack ultimately proved considerably more compatible once everybody was awake. Gallagher continued appearing regularly in movies throughout the remainder of the decade. His credits included To Gillian on Her 37th Birthday, Malice, The Underneath and American Beauty. In the latter, he played real-estate executive Buddy Kane, who becomes involved with Annette Bening's character, Carolyn Burnham. By the beginning of the 2000s, Gallagher had already accumulated an extensive career in theater and film. Then television handed him the role that would introduce him to an entirely new generation. In 2003, Fox premiered The O.C., a drama centered on Ryan Atwood, a troubled teenager from Chino who is taken into the wealthy Newport Beach home of attorney Sandy Cohen and his family. Gallagher played Sandy. Sandy Cohen could easily have become another wealthy, emotionally distant television father. Instead, Gallagher turned him into the moral center of the series: compassionate, funny, principled and generally willing to help somebody even when doing so threatened to make his already complicated household more complicated. And it frequently did. Sandy was married to Kirsten Cohen, played by Kelly Rowan, and father to Seth Cohen, played by Adam Brody. After bringing Ryan, played by Benjamin McKenzie, into the family, Sandy effectively became his father as well. Gallagher appeared throughout all four seasons of The O.C. from 2003 until 2007. His performance gave the teen-oriented drama an important adult foundation and made Sandy Cohen one of television's more memorable fathers. The character also possessed something rarely encountered in fictional wealthy communities: common sense. Not that anyone around him was required to use it. The popularity of The O.C. transformed Gallagher into a familiar face for viewers who had not been around for sex, lies, and videotape or The Player. Suddenly an actor who had already been working professionally for more than 25 years had another defining role. His career after The O.C. remained remarkably busy. Gallagher appeared in television series including Californication, Rescue Me and Covert Affairs. In the latter, he played CIA official Arthur Campbell, appearing regularly throughout the show's run. He also took a recurring role as William Dodds, the NYPD Deputy Chief who becomes the commanding officer overseeing the Special Victims Unit on Law & Order: Special Victims Unit. The role brought Gallagher into another of television's longest-running franchises. Gallagher later joined the cast of Netflix's Grace and Frankie as Nick Skolka, a wealthy businessman who becomes romantically involved with Jane Fonda's character, Grace Hanson. Appearing opposite Fonda, Lily Tomlin, Martin Sheen and Sam Waterston placed him among another formidable ensemble of veteran performers. He has also appeared in Zoey's Extraordinary Playlist as Mitch Clarke, Zoey's father. The musical comedy-drama provided Gallagher with the opportunity to combine his television acting with the singing abilities he had developed during his Broadway career. Gallagher's musical background has always been a substantial part of his professional life. In addition to Broadway, he released an album titled 7 Days in Memphis in 2005. He also performed the song “Don't Give Up on Me” on The O.C., giving Sandy Cohen yet another ability to add to the résumé of television's unusually competent father. Gallagher returned prominently to Broadway in 2015 opposite Kristin Chenoweth in the revival of On the Twentieth Century. His decades of stage work distinguish him from performers whose careers have remained primarily in front of cameras. Long before Sandy Cohen began dispensing fatherly wisdom in Newport Beach, Gallagher was singing and acting before live audiences in New York. His personal life has been considerably more stable than those of many characters he has portrayed. Gallagher married Paula Harwood in 1983, after the couple met while attending Tufts University. They have two children, James and Kathryn. Their daughter Kathryn Gallagher followed the family into entertainment and became an actress and singer in her own right. She appeared in the Broadway production of Jagged Little Pill, earning a Tony Award nomination, and has built a career across theater, television and music. Gallagher's longevity is one of the most impressive aspects of his career. He has moved from Broadway musicals to independent cinema, major Hollywood films, prime-time dramas, cable television, streaming series and back to Broadway without ever becoming permanently confined to one type of character. Some audiences will always associate him with Peter Callaghan, the handsome stranger whose lengthy nap created the entire plot of While You Were Sleeping. Others will remember the deeply flawed John Mullany in sex, lies, and videotape. Another generation knows him almost exclusively as Sandy Cohen, the endlessly patient father who opened his home to Ryan Atwood on The O.C. That versatility has allowed Peter Gallagher to remain active for decades in an industry that frequently moves on to the next new face with astonishing speed. Of course, having perhaps the most recognizable eyebrows in American television cannot possibly have hurt. Those things deserve their own SAG cards. ```json { "@context": "http:\/\/schema.org", "@graph": [ { "@type": "Article", "author": { "@id": "https:\/\/marktheday.info\/#paul_stallibrass_144f731fa4" }, "dateModified": "2026-08-18T19:45:39Z", "datePublished": "2026-08-18T18:54:19Z", "description": "Explore Peter Gallagher's life and career, from Sandy Cohen on The O.C. and While You Were Sleeping to Broadway, film and television.", "headline": "Peter Gallagher", "image": { "@id": "https:\/\/marktheday.info\/#defaultLogo" }, "inLanguage": "en-GB", "mainEntityOfPage": { "@type": "WebPage", "url": "https:\/\/marktheday.info\/peter-gallagher" }, "publisher": { "@id": "https:\/\/marktheday.info\/#defaultPublisher" }, "url": "https:\/\/marktheday.info\/peter-gallagher" }, { "@type": "Person", "name": "Paul Stallibrass", "@id": "https:\/\/marktheday.info\/#paul_stallibrass_144f731fa4" }, { "@id": "https:\/\/marktheday.info\/#defaultLogo", "@type": "ImageObject", "url": "", "width": 0, "height": 0 }, { "@id": "https:\/\/marktheday.info\/#defaultPublisher", "@type": "Organization", "url": "https:\/\/marktheday.info\/", "logo": { "@id": "https:\/\/marktheday.info\/#defaultLogo" }, "name": "" } ] } ```
