Miguel Arteta has found his leading lad…

Disney has cast Ed Oxenbould to portray the title character in the film adaptation of the children’s book Alexander And The Terrible, Horrible, No Good, Very Bad Day.

The young actor will join Steve Carell and Jennifer Garner in the film, which will be directed by the 48-year-old Puerto Rican filmmaker.

The film will be an adaptation of Judith Viorst’s popular book that parents read to their kids over and over.

The film, which will be released in theaters on October 10, 2014, follows young Alexander through the mishaps of a terrible day for his family after he wishes they all would experience the same troubles he does.

Oxenbould was picked after a lengthy search.

Arteta’s credits include helming the CW’s The Carrie Diaries, as well as the films Cedar Rapids and Youth In Revolt.
