Anthony is related to actor Danny DeVito (Anthony's grandfather and Danny's father were first cousins.) They met once in 1982, at Danny's party for extended family to celebrate his wedding to Rhea Perlman. Anthony was 16 at the time.
Anthony shot a scene for BROS, playing a liberal ally at a Pride Parade. It was unfortunately cut from the film but can be seen on the Blu Ray/DVD/Digital Edition as the deleted scene "Pride Fight.".
