A handsome, former stage actor turned lead and second lead on TV and in films, Sheridan is cable of projecting a range from good-guy niceness to cop toughness. Bitten by the acting bug after a knee injury ruined his chances for a dance career, he left California to pursue stage work, eventually scoring several impressive successes off and on Broadway, including a Tony nomination for his work in the 1987 revival of "All My Sons".
Sheridan made his film debut with a bit part in "Jumpin' Jack Flash" (1985). He moved on to larger roles, including a co-starring part as the jealous boyfriend in "Distant Thunder" (1988) and the lead in a TV series Shannon's Deal" (NBC, 1990-91) created by John Sayles. On the short-lived series, he was a highly-paid corporate lawyer who left the high life to return to the trenches as a district attorney.
On the heels of the TV series came the release of "Stanley & Iris" (1990) in which Sheridan portrayed Jane Fonda's angry, unemployed brother-in-law. He then segued to playing love interests for leading ladies: he was Harley Jane Kozak's estranged husband in "All I Want for Christmas" (1991); Melanie Griffith's detective partner who wants much more in "A Stranger Among Us" (1992); and a dashing pilot who romances Annabella Sciorra in "Whispers in the Dark" (1992).
Sheridan had success on the small screen as the villainous Randall Flagg in "Stephen King's 'The Stand'" (ABC, 1994) and that same year starred opposite Meredith Baxter in "My Breast" (CBS). He joined the ensemble cast of the medical drama "Chicago Hope" (CBS) as Dr. John Sutton for one season (1995-96). More recently, Sheridan was cast as Mercedes Ruehl's husband confounded by her newfound interest in her heritage in the 2000 CBS "Hallmark Hall of Fame" production "The Lost Child".
