Fan CastingBoss Baby 2017

Timothy "Tim" Templeton, an imaginative 7-year-old boy, relishes his parents' attention and is horrified when a new baby brother arrives. Baby, whom Tim saw arrive in a taxi, clad in suit and tie, and carrying a briefcase, behaves normally around the adults, crying for attention and food and diapers all day and night. However, Tim, who is fast growing jealous, sees Baby talking in an adult voice and behaving like an adult whenever Mr. and Mrs. Templeton aren't looking. One day, Baby holds a staff meeting with other toddlers and infants, under the guise of a neighborhood play date. Timothy attempts to record them on a cassette tape, but he is seen and chased by Baby and his cronies. The parents see this as the children playing in the yard. When Baby destroys one of Tim's favorite toys, Tim attempts to slingshot him out a window, but his parents stop him and he accidentally slingshots the tape into the street, where a car smashes it. Tim and Baby are grounded until they learn to get along.
