Besides Carell backing up his former office pal, Krasinski's "IF" will also see his wife and former "A Quiet Place" co-star Emily Blunt joining the film's colorful cast of characters. The imaginary entourage of IFs will also boast the talent of Matt Damon, Maya Rudolph, Phoebe Waller-Bridge, Vince Vaughn, and Sam Rockwell.

So far, the movie has already received a positive reaction when the team debuted footage at CinemaCon. Krasinski told Deadline, "I had this idea for a movie years ago about imaginary friends. I want this movie to be believing in something bigger...and getting you through something bigger, that's possible." With a pitch like that, you can expect heartstrings to be yanked hard and it fulfills Reynolds' description of "IF" being "a live-action Pixar film."

Fleming played Judith Grimes in 53 episodes of AMC's "The Walking Dead," so the magical world here must be a nice break from the post-apocalyptic setting. "IF" also marks Fleming's first major feature role in a big-screen project — though she previously played young Rey in "Star Wars: The Rise of Skywalker."

"IF" arrives in theatres on May 17, 2024.
