Who seems to be in every movie or TV project these days? If you answered Tom Hanks, Morgan Freeman, Robert De Niro, or Julia Roberts, you’d be wrong. While these actors have been in plenty of movies, they don’t even break the top ten.

The “Man of a Thousand Voices,” Mel Blanc is regarded as the actor who’s racked up the most acting credits — at 1,228 — voicing Bugs Bunny, Porky Pig, Daffy Duck, and many, many more cartoon characters since the 1930s.

Though somewhat overshadowed by his younger sister, Julia Roberts, and his up-and-comer daughter, Emma Roberts, Eric Roberts easily tops the list as the hardest working actor in Hollywood, with roughly 720 acting credits to his name.

Following a rough childhood, LA-born Mexican actor Danny Trejo spent much of his youth in jail, eventually undertaking a 12-step rehabilitation program that changed his life by introducing another recovering addict and securing him a role in the 1985 film "Runaway Train." Since then, Trejo has proven to be a professional on set, a mentor to young talent, and a go-to favorite for established directors such as Robert Rodriguez, racking up roughly 446 credits.

Appearing consistently on our screens since 1972 — a career that spans 50 years — it seems like Samuel L. Jackson is in every movie. A highly prolific actor, Jackson’s landed roughly 208 credits from 1990s hits "Pulp Fiction" (1994) and "Star Wars: The Phantom Menace" (1999), to Black Snake Moan (2006), and Django Unchained (2012).
