Eazy-E's son is feeling disappointed after he was left out of the cast of upcoming N.W.A. biopic Straight Outta Compton.

Lil' Eazy-E, real name Eric Wright, Jr., had hoped movie bosses would let him play his late father in the new movie about the legendary hip-hop group, but newcomer Jason Mitchell has been given the role instead.

The 30 year old tells Tmz.com he is disappointed with the decision, adding, "I am my father. I look like him. I sound like him."

Ice Cube's son O'Shea Jackson Jr. will portray his own father in the film, but Dr. Dre's son Curtis Young also faced disappointment when the role of his dad was given to actor Marcus Callender.

Wright, Jr., who was just 11 years old when his rapper father died from an AIDS-related illness in 1995, previously said of the movie role, "I'm the perfect man for the role. Who better to play him in the N.W.A. days? Like father, like son - no make-up needed."
