Yeah, I'm only familiar with Marvin the Martian in Duck Dodgers in the 24½th Century. It's interesting that the character goes back as far as 1948. As you say, Bugs would work just as well as a foil. The main problem with Marvin the Martian as a main character might be that, apart from the eyes, he doesn't have a face. I believe his proposed antagonist was Santa Claus. http://en.wikipedia.org/wiki/Marvin_the_Martian#Planned_film I wonder how much money WB spent on that turkey.
