Part of the Daly acting dynasty, which includes his Emmy-winning father James and his Emmy-, Golden Globe- and Tony-winning older sister Tyne, Tim may not quite live up to his relatives in accolades but surpasses them in popularity. Although he made an auspicious film debut in the 1982 coming-of-age drama Diner, movies wouldn't be kind to Daly over the years. TV, however, was the ideal medium for his talents, and in 1990 he landed his seminal small-screen role on Wings as an adorable, levelheaded pilot who tolerated the other characters' wacky shenanigans. During his seven-year tenure on the sitcom, Daly wisely sought out extracurricular projects, mostly TV-movies that allowed him to play against type, such as cult leader David Koresh in In the Line of Duty: Ambush in Waco and a convicted killer in Witness to the Execution, although he never quite shed his hunky image. After Wings' cancellation, Daly kept busy, voicing the title character in the animated Superman series, and popping up in supporting film roles in between short-lived series (the remake of The Fugitive, Eyes, The Nine). In 2007, he found TV stability once again when he was cast as Dr. Pete Wilder in the Grey's Anatomy spin-off Private Practice.
