Tommy Chong is perhaps best known as one-half of the legendary cannabis-fueled comedy duo Cheech & Chong, which minted six gold records and released eight films during their reign, for which Chong also co-wrote and directed. Up in Smoke (1978), the highest grossing comedy of the time, topped $100 million at the box office. Chong is also highly recognizable from his role as the aging hippie photo store worker Leo on That 70s Show, which aired on television from 1998 to 2006 in its original run.
