Gaul has dubbed comedian Nick Swardson in several films, Ethan Supplee on My Name Is Earl and other projects, Toby Jones in The Mist, and the dog Sebastian in the Beverly Hills Chihuahua series.

Joe: Retaliation, The Fifth Element, and episodes of Boston Legal, JAG, Buffy the Vampire Slayer, and the animated Superman.
Gaul has also been heard in the localizations of video games Star Trek: Elite Force II, Assassins Creed: Black Flag, and others. His on-camera credits include the long-running German series Der Alte and a supporting role in the 2009 English-language film The Last Station (with Helen Mirren and James McAvoy), as Donald Sutherland's house servant.
