Can you help me find a Samuel L. Jackson Quote (see details!)

Ok, Google and Brainy Quotes and the IMDB aren’t helping. Anyway, the gist of Jackson’s quote is buried in one of his reflections on Django Unchained and the portrayal of African Americans. Not the controversial issue of him challenging a reporter to say the N-word. (Although the coaxing of the reporter is quite entertaining, if this article is to be believed.)

Anyway, the way I remember the quote was along the lines of Jackson saying, were you put off by the role, and Jackson said: “A gig is a gig” or something along those lines. Any help?

Oh, and I found this quote on IMDB which made me crack up: on Snakes on A Plane: I stand by that movie!

Anyway, if anyone can help me find that quote, it would be really useful. Thanks!
