I think we can all agree that Elf [1] is a classic (well, as long as you don't watch the Honest Trailer [2]). The 2003 Christmas movie, directed by Jon Favreau [3], turns 15 this year, so in honor of the milestone, Rotten Tomatoes got Favreau and star Will Ferrell [4] on the phone to take everyone behind the scenes and break down their favorite moments from the film.

If you're still quoting Elf [5] as we speak, then it's definitely worth a watch; Favreau and Ferrell look back on how they shot the movie guerrilla-style on the streets of New York City, the reaction to seeing Ferrell in his elf getup, and the one scene that brought Ferrell to tears. Check it out above, then take our quiz to see how well you know Elf [6]!
