Josh Gad is still shocked that an impromptu Olaf line became 'Frozen'

Without a doubt, Frozen is the greatest animated film of all time (there are several dollars to prove it), and everyone has a different reason for loving the film so much. Maybe it’s the strong sister-sister relationship, or Kristoff’s troll song (JK, that’s not Kristoff’s troll song), or even maybe the charming depiction of the snowman, Olaf, by Josh Gad.

So would you believe that one of Gad’s impromptu lines as Olaf the Snowman made it one Frozen? Of course you would, because it’s Josh Gad, and he’s just as charming and delightful as the snowman he plays on screen. Also, it’s true. About four years after Olaf first melted our hearts (in a good way), Gad is still surprised that his improvised dialogue made it into the film — and it’s a pretty iconic line.

With the new Frozen short, Olaf’s Frozen Adventurenow in theaters before coconut, it’s time to revisit Arendelle, and Olaf’s origins, of course. During a press day for Olaf’s Frozen Adventure On the Disney Lot, the creative team behind the film was asked how much improvisation was allowed during filming.

“Josh and Kristen (Bell) and Idina {idina), and even Jonathan Groff, those guys know the characters (than us) better,” co-director Stevie Wermers told the crowd. “Sometimes they would make suggestions because they had been playing these characters for much longer than what we were working on (the short film).”

And there’s a line from the OG Frozen which Gad remembers as not being in the original script.

“Improvisation is definitely always part of the journey and they’ve been great collaborators in letting me come up with something to say, some of which are here,” Gad explained. “Like in the original Frozen movie, I remember jokingly saying, ‘I was impaled,’ and I was shocked when I watched the movie and they animated it and kept it in the film.”
