Will Ferrell revealed during an interview on the “Messy” podcast (via IndieWire) that his late “Elf” co-star James Caan was not a fan of his performance as Buddy the Elf until he saw the final cut of the Christmas movie at the film’s premiere. Ferrell said that Caan told him at several points during production that he just wasn’t funny, although Ferrell admitted to driving Caan “crazy” on set while playing the overenthusiastic Buddy.

“James Caan, may he rest in peace, we had such a good time working on that movie,” Ferrell said. “He would tease me. I like to do bits but I’m not like ‘on’ all the time. In between set ups, [Caan] would be like, ‘I don’t get you. You’re not funny.’ And I’m like, ‘I know. I’m not Robin Williams.’ And he was like, ‘People ask me: “Is he funny?” And I’m like, “No, he’s not funny.”‘ It was all with love but at the same time…”

It wasn’t until Ferrell and Caan were walking out of the movie theater at the “Elf” premiere that Caan took him aside and gave him “the best compliment.”

“He was like, ‘I’ve got to tell you: I thought everything you were doing while we were filming was way too over the top. Now that I see it in the movie, it’s brilliant,’” Ferrell remembered. “But I love that the whole time, he’s not acting. He’s truly annoyed with me. He’s like, ‘Can this guy shut the fuck up? Jesus.’ I literally drove him crazy in that movie, just acting like that kid. But that was the funniest thing, him walking out of the theater and shaking his head and going ‘it’s brilliant.’”

Caan starred in “Elf” as Buddy’s biological father. The movie, directed by Jon Favreau, endures as a Christmas classic a decade after its release, where it earned over $220 million at the worldwide box office. Ferrell previously revealed that he once turned down a $29 million offer to star in an “Elf” sequel.

“I would have had to promote the movie from an honest place, which would’ve been, like, ‘Oh no, it’s not good. I just couldn’t turn down that much money,’” Ferrell said about the simple decision to reject “Elf 2.” “And I thought, ‘Can I actually say those words? I don’t think I can, so I guess I can’t do the movie.’”
