Enter a world you have to believe to see in a live-action/cg-animation hybrid family comedy from the wild imagination of writer-director John Krasinski. IF tells the story of a young girl who discovers that she can see everyone's imaginary friends - and what she does with that superpower - as she embarks on a magical adventure to reconnect forgotten IFs with their kids. IF features an unbelievable all-star cast that includes Ryan Reynolds, John Krasinski, Cailey Fleming, and Fiona Shaw, as well as the voices of Steve Carell, Phoebe Waller-Bridge, Matt Damon, Sam Rockwell, Awkwafina, Louis Gossett Jr, Emily Blunt, and many more as the wonderfully unique characters that all showcase the incredible power of a child's imagination.
