George Clooney, Matt Damon and more A-listers who voiced animated characters in John Krasinski's 'IF'

Krasinski directed, wrote, produced and starred in the 2024 movie 'IF'

John Krasinski's newest movie "IF" is full of A-list stars voicing the many animated characters in the film. 

"IF," a movie directed, written and produced by Krasinski, is about a young girl named Bea (Cailey Fleming) who discovers that she holds the power of seeing people's imaginary friends, called IFs for short. 

Her neighbor, Cal (Ryan Reynolds), possesses the same unique ability. The two team up in order to help forgotten IFs reconnect with kids. This plot line leaves a lot of room for actors to voice the adorable animated characters making up the large majority of the cast.

"I've always wanted to make a movie for my kids, but I wasn't sure what to do," Krasinski told CBS Mornings. "I had this idea to do something with imaginary friends, but I wasn't sure what my take on it would be."

"I spent hours standing in the threshold of a door with Emily [Blunt], watching our girls go into this magical world that as parents, were not invited into," Krasinski told the outlet. "It wasn't just the joy and how much fun they were having, it was the authenticity, the idea that they were themselves, and they were fearless, and they were doing all these amazing things, doing all these amazing voices and then the pandemic hit. I saw their lights starting to go out, and I saw that the world started to seep in, and that is the definition of growing up."

This movie marks the fourth film Krasinski has directed. His directorial debut was in 2016 with the movie "The Hollars." He then directed "A Quiet Place" (2018) and "A Quiet Place Part II" (2020). 

Before directing movies, he directed a few episodes of "The Office."

"It was just a joy from beginning to end, and I jumped at the chance to work with him again, partly just to be with him. He’s a good friend, and I hadn’t seen him in a while, so it was nice to catch up."
