Behind the Scenes

Phillip Fathom is one of the most recent breakout characters in the Thrilling Adventure Hour, due in no small part to Hal Lublin's fantastic Christian Bale-styled voice acting. Fathom has spun off onto a segment in both the OGN and the 2012 Christmas special in addition to frequent appearances in Captain Laserbeam episodes.

Hal has said in interviews that doing the Fathom voice does very little damage to his throat, but the sheer amount of oxygen needed to project makes him dizzy after a long speech.
