James Marsden and Joan Cusack have joined the cast of Kristen Wiig's new comedy Welcome To Me.
The Bridesmaids star plays Alice, who suffers from dissociative personality disorder. When she wins the lottery she decides to use the money to fund a talk show about herself, but her obsession with fame begins to alienate her friends and family.
The film is being directed by Fully Loaded's Shira Piven and is the debut film from comedy writer Eliot Laurence.
Producers include Wiig and Will Ferrell.
Welcome To Me will begin shooting in California in August.
