Calah Lane and Timothée Chalamet talk about playing unexpected friends Noodle and Willy Wonka in this exclusive look at the upcoming film Wonka.

In the exclusive featurette, Chalamet, Lane and director Paul King opened up about what it’s like to bring this new story about the iconic chocolatier to life. In particular, they talked about how Wonka’s friendship with Noodle helped him on his journey to become the character we know of today.

“It’s almost like Wonka and Noodle were destined to be best friends,” said Chalamet.

Lane said that her character brings the smarts to the operation, whereas Wonka has all the creative ideas.

“He [is a] chocolate maker and she’s the one that’s got the brain and she’s like, ‘Okay, so this is what we’re gonna do,” she said. She added about Chalamet, “He’s knows how to put a smile on my face. He knows how to put a smile on a lot of people’s faces.”

King added about the characters, “What she [Noodle] brings to Willy is cynicism and reality and what he brings to hear is the power of dreams and imagination.”
