Snakes on air planes?

[Sacred Jellybean]

From imdb's trivia:

Samuel L. Jackson only signed on for this film because of the title. It was later changed to "Pacific Air Flight 121", but Jackson demanded they reverse the change. "We're totally changing that back. That's the only reason I took the job: I read the title."

I don't know how good of a source it is, but that's funny, if true.
