A former professional baseball player, Pat Flaherty was seen in quite a few baseball pictures after his 1934 screen debut. Flaherty can be seen in roles both large and small in Death on the Diamond (1934), Pride of the Yankees (1942), It Happened in Flatbush (1942), The Stratton Story (1949, as the Western All-Stars coach), The Jackie Robinson Story (1950) and The Winning Team (1952, as legendary umpire Bill Klem). In 1948's Babe Ruth Story, Flaherty not only essayed the role of Bill Corrigan, but also served as the film's technical advisor. Outside the realm of baseball, he was usually cast in blunt, muscle-bound roles, notably Fredric March's taciturn male nurse "Cuddles" in A Star is Born (1937). One of Pat Flaherty's most unusual assignments was Wheeler and Woolsey's Off Again, On Again (1937), in which, upon finding his wife (Patricia Wilder) in a compromising position with Bert Wheeler, he doesn't pummel the hapless Wheeler as expected, but instead meekly apologizes for his wife's flirtatiousness!
