Here’s the trailer for the Disney’s live-action take on the classic picture book Alexander and the Terrible, Horrible, No Good, Very Bad Day, which stars Steve Carell and Jennifer Garner as the parents and has a bunch of comedy cameos from Megan Mullally, Donald Glover, Jennifer Coolidge, and Dick Van Dyke. The film hits theaters on October 10th, which should be plenty of time for you to finish reading the original book beforehand.
