During an interview with The Guardian back in 2006, Will Ferrell claimed he turned down a whopping $29 million offer to appear in an "Elf" sequel. 

"It wasn't difficult at all," he stated. "I remember asking myself: Could I withstand the criticism when it's bad and they say, 'He did the sequel for the money?' I decided I wouldn't be able to. I didn't want to wander into an area that could erase all the good work I've done – but you watch, I'll do some sequel in the future that's crap."

Ferrell later added, "I never liked [the idea of a sequel] – $29 million does seem a lot of money for a guy to wear tights, but it's what the marketplace will bear. It's insane, but it's not my call. The studios perpetuate it and they make it hard to say no."

Of course with a net worth of $160 million, per Celebrity Net Worth, $29 million seems like a drop in the bucket.
