Chris Buck says that the success of Frozen has been 'phenomenal' but they weren't thinking about that when they were making the movie.
Chris Buck and co-director Jennifer Lee picked up the Best Animation Film gong for Frozen at the Baftas; following on from success at the Golden Globe and Annie Awards.
Speaking in the post-win Bafta press conference, Buck said: "We really just tried to make a movie that would make people laugh, cry and just have a good time with. It has been phenomenal.
"We have the sing-a-long version now, and it is incredible to go and see that."
But Jennifer Lee says all of these success means that they are going to have to push harder with their next project.
"I think now we will have to work harder and harder, because I don't know how to top this feeling. I think the crew expects us to push even harder next time."
Frozen saw off the challenge from Despicable Me 2 and Monsters University to claim the Bafta, and is the favourite for Oscar glory next month.
