More than anything, the IF movie cast has got movie audiences excited about John Krasinski’s next feature project. The live-action/animated fantasy comedy packs a star-studded ensemble cast, from comedians to action and drama stars. Although credited as an original screenplay, several audience comments have likened IF to Cartoon Network’s Foster’s Home for Imaginary Friends.
IF, an abbreviation for Imaginary Friends, follows a young girl, Bea, who, after a traumatic experience, discovers she can see people’s childhood Imaginary Friends. When she also discovers her neighbor has the same ability, they try to reconnect these Imaginary Friends with their long-lost, grown-up friends. IF is John Krasinski’s return to the director’s chair after a four-year absence. To help breathe life into the characters, here are the IF movie cast and the characters they play.
Cailey Fleming as Bea
17-year-old Cailey Fleming leads the IF movie cast, playing the main protagonist, Bea. With the ability to see people’s imaginary friends, Bea decides to assist, with the help of her neighbor, Cal, in reconnecting the IFs to their human counterparts. Cailey Fleming, whose acting career began at 8, made her film debut playing a younger Rey in Star Wars: The Force Awakens (2015). Her breakout and most prominent role was as Judith Grimes in The Walking Dead (2018–2022).
Ryan Reynolds as Cal
Ryan Reynolds plays Cal, Bea’s older neighbor with a similar ability to see IFs. Besides being one of the movie’s producers, Reynolds delivers an unparalleled performance as a supporting character.
