Mark Hamill is actually VERY prolific. He's most known for his villain roles (The Joker, Emperor Ozai, Skeleton King in Super Robot Monkey Team Hyper Force GO!, Mr. Salacia in Metalocalypse, etc) but he's also Skips on Regular Show, the Fear Feaster on Adventure Time, Turtle on My Friends Tigger and Poo, Stickybeard on Codename: Kids Next Door, Larry 3000 on Time Squad... he's been in damn near everything and virtually all of his acting work since 1992 has been as a voice actor. Mark Hamill gets SERIOUS work.[DOUBLEPOST=1442769893,1442769730][/DOUBLEPOST]
On the plus side, Carrie Fisher knows script writing and is a excellent script doctor for Hollywood.
