The turning point in the Mars Callahan career came in 2002 with the release of Poolhall Junkies.

Business Ventures and Investments

Personal Life
Mars Callahan maintains a relatively private personal life away from the Hollywood spotlight. He is married to Therese Depaepe, and the couple has a family.
