The background of Irish-born comic actor J. Pat O'Malley has frequently been misreported in source books because his credits have been confused with those of silent film star Pat O'Malley. J. Pat started out in the British musical halls, then came to the U.S. at the outbreak of WWII. Achieving radio fame for his versatile voicework, O'Malley carried over this talent into the world of animated cartoons, providing a multitude of vocal characterizations in such Disney cartoon features as Alice in Wonderland (1951) and 101 Dalmatians (1961), among others. The portly, leprechaunish O'Malley essayed on-camera character parts in films like Witness for the Prosecution (1957) and Mary Poppins (1965). He was a near-habitual TV guest star, with appearances in several fondly remembered Twilight Zone episodes; he also worked extensively on Broadway. J. Pat O'Malley had regular roles on the TV sitcoms Wendy and Me (1964) and A Touch of Grace (1973).
