The Croods features the voices of Stone, Nicolas Cage and Ryan Reynolds in the tale of a caveman family who explore the world after a severe earthquake.
In an interview with Flicks and Bits, Stone reflected on her first viewing of the DreamWorks comedy.
"That was incredible, it was amazing," she recalled. "I think The Croods has elements of all of my favourite movies, which is that it's not just funny and it's not just heartbreaking, it takes you on a journey throughout the entire film."
Stone went on to reveal that she even shed a tear while watching the prehistoric family's journey to find a new home.
"I cried watching it, and I laughed, and I just went along for the ride and enjoyed myself the entire time," she admitted.
The star further explained. "Throughout recording it you come in and you're doing different things on different days, and then when you see how everything plays out in the end you realise that the messages - which there are many in the film - stick with you after the fact, but you're not sitting there watching it thinking about the 'themes', you're sitting there enjoying this family.
"I loved that. It's different than any other animated movie that I've seen, in a sense that it feels so true to life the whole entire time - even though we are in the Stone Age."
Catherine Keener, Clark Duke and Cloris Leachman also lend their voices to the animated film.
The Croods opens on March 22 in the US and the UK. Watch a trailer below:
