Ferrell spoke about Caine on the 'Messie' podcast, revealing that Caine initially received some criticism for Ferrell's performance as Buddy the Elf in the Christmas movie.

During production, Caine would often tease Ferrell, saying, "I don't understand you. You're not funny."

Ferrell would playfully reply, "I know! I'm not Robin Williams."

Despite these humorous exchanges, Ferrell shared that Caine's irritation with Buddy's on-screen behavior actually helped strengthen the comedic dynamic between their characters.

The late star had planned to gradually build up his character's frustration, but he chose to use it for the climax scene, reports Aceshowbiz.com.

Ferrell praised Cain's strategic approach, admitting that he was "completely right."

Caine's impression of Ferrell's performance changed dramatically after seeing the final film at its premiere.

While leaving the theater, Caine said to Ferrell: "I thought what you were doing was too much when we were filming, but now that I've seen it in the movie, it's brilliant."
