Often plays a villainous character.

Son of English actress Eileen Bell.

Studied in New York City with Ellen Burstyn.

Is probably best known as Jigsaw/John Kramer in the "Saw" movies.

Has never been, and to this day is not, a fan of horror films, despite playing his menacing character Jigsaw in the "Saw" trilogy.

Donated two vials of his own blood to be mixed with red ink for 1000 posters to help promote Saw III (2006). All proceeds went to the American Red Cross.

His favorite Saw traps are the Jaw Splitter from the first film and the Syringe Pit from the second.

In addition to being an actor he is also a Little League baseball coach.

Considers Saw II (2005) his favorite out of the "Saw" trilogy.

He had a small role in Goodfellas (1990), with Joe Pesci. Pesci later played David Ferrie in JFK (1991), the same role Bell played in Ruby (1992).

Splits his time with his wife and two children between his homes in New York and Los Angeles.

Was an extra in the classic comedy Tootsie (1982). He can be seen briefly as a waiter in the party scene in which Michael (Dustin Hoffman) tries to pick up Julie (Jessica Lange) and gets water thrown in his face. Tobin can be seen crossing the camera at the very beginning of the scene.
