In the script, written by Lisa Cholodenko and Rob Lieber, the boy has a terrible day and wishes his family experienced his suffering, which they later do.

Thorne will play the gooey girlfriend of Alexander’s very cool older brother.

21 Laps and The Jim Henson Co. are producing the family film, which is slated for an Oct. 10, 2014, release.
