The Way, Way Back has rounded out its cast, adding Rob Corddry, Amanda Peet and Maya Rudolph. The film already features an all-star lineup of Steve Carell, Toni Collette, Liam James and Sam Rockwell.

The comedy follows a teenage boy (Liam James), who forms a friendship with a local water-park manager (Sam Rockwell). In one summer's time, this new friend helps him come face to face with his abusive stepfather (Steve Carell) and repair his relationship with his mother (Toni Collette).

The Descendants writers Nat Faxon and Jim Rash are directing the project, as well as playing a pair of water park employees.

The film begins shooting next week in Massachusetts.
