Steve Carell and Jennifer Garner star in this family comedy based on the children's book by Judith Viorst. Eleven-year-old Alexander Cooper (Ed Oxenbould) has the worst day ever, experiencing one mishap after the other. His dad Ben (Carell), mum Kelly (Garner) and older siblings Anthony (Dylan Minnette) and Emily (Kerris Dorsey) always seem to have sunny dispositions and fail to empathise with his misery. However, when his family find themselves in terrible situations of their own, Alexander begins to understand that to have good days you must also have bad ones. The film co-stars Bella Thorne, Jennifer Coolidge, Megan Mullally and Donald Glover.
