Leo DiCaprio and Mel Gibson are out, Rupert Everett and Angela Bassett are in

This week’s casting news begins with some de-casting. Leonardo DiCaprio has officially bowed out of “American Psycho,” reportedly after a reading with Cameron Diaz for Oliver Stone. The film has now been returned to original director Mary Harron (“I Shot Andy Warhol”), who was bumped after the multimillion dollar star showed interest. Also, Mel Gibson has decided not to star in Gregory Nava’s (“Why Do Fools Fall in Love”) adaptation of “A Tale of Two Cities.” He is now looking for another acting role to squeeze in before directing his version of Ray Bradbury’s “Fahrenheit 451.”

Rupert Everett, meanwhile, has become the go-to guy for gay roles after “My Best Friend’s Wedding.” He has joined “Unconditional Love” as a grouch whose famous-male-singer lover is killed and who teams with his lover’s biggest fan to solve the murder. The film was cowritten by “Wedding” director P.J. Hogan.

Angela Bassett, now starring in “How Stella Got Her Groove Back,” is negotiating for the “ER”-meets-“Ghost” love story “Trauma.” Bassett would play a quiet cleaning woman who forms a relationship with a surgeon when she starts giving him healing tips passed on to her by the ghost of another doctor.

Robin Williams is discussing reteaming with his “Good Will Hunting” director, Gus Van Sant, in “Don’t Worry, He Won’t Get Far on Foot,” the story of real-life quadriplegic cartoonist John Callahan. Callahan became an alcoholic after the car accident that paralyzed him, but stopped drinking when he began drawing his often perversely funny cartoons.

Finally, Laura Linney, who played Jim Carrey’s syrupy wife in “The Truman Show,” will star in the TV-movie version of the much-performed play “Love Letters.” The story follows two childhood friends who exchange the titular missives throughout their lives. It will be directed by Stanley Donen, who received an honorary Oscar this year for such classic musicals as “Singin’ in the Rain” and “Funny Face.”
