Bill Kopp: Co-directed "Hare and Loathing in Las Vegas" with Peter Shin.
Bob Clampett: Directed 11 "official" Bugs Bunny shorts, but also directed "Any Bonds Today?" and "A Corny Concerto" (even though those aren't considered official Bugs Bunny shorts) as well as his cameos in "Patient Porky" and "Crazy Cruise".
Cal Dalton: Co-directed "Hare-Um Scare-Um" with Ben Hardaway.
Chuck Jones: Directed 43 of Bugs' shorts on his own, as well as two of the four "Proto-Bugs" shorts. He co-directed "Baton Bunny" with Abe Levitow, and co-directed "Abominable Snow Rabbit", "Compressed Hare", "Hare-Breadth Hurry", "Mad as a Mars Hare", and "Transylvania 6-5000" with Maurice Noble. He also directed the modern short "From Hare To Eternity".
Life Imitates Art: Sort of. After Bugs appeared as a U.S. Marine in "Super-Rabbit", the real Marines made him one. He was officially inducted into the force as a private, complete with dogtags. The character was regularly promoted until Bugs was officially "discharged" at the end of World War II as a Master Sergeant.
