Cruel Intentions actress Selma Blair is also in talks to sign for the independent movie, which stars Hope Davis and Dermot Mulroney.
The film sees Davis's character Bunnie get a second chance at her marriage after she forgets the last 15 years of her life, including the fact that she is having an interracial affair with neighbour Simon (McBride). Dermot Mulroney plays her husband Jack, Max Thieriot her religious, right-wing son and Evan Ross plays Simon's son.
Blair will take the role of a lesbian teacher who is romantically involved with a student (Zima), while Anwar portrays Jack's power-mad work colleague.
Rapper Bow Wow and Jermaine Williams star as wannabe thugs and Brittany Robertson plays Jack's daughter.
The film, written by Mark Lisson, is the big-screen debut for director Vivi Friedman, who previously worked on adverts in Finland.
Shooting is scheduled to begin in LA next month.
