Washington, Mar 19 : Sylvester Stallone has defended his decision to cast rapper 50 Cent in his forthcoming movie, and said that fans’ criticism for the choice is “not fair.”

The ‘Rocky’ star has roped in the most notorious action stars, including Jet Li, Mickey Rourke and Jason Statham, for his all-star action film ‘The Expendables’.

Currently, the shooting for the film is going on in Brazil.

Initially, Forest Whitaker was to appear in the movie as Agent Will Sands.

But he had to drop out due to scheduling conflicts after shooting on the Stallone''s film was pushed back.

Stallone later gave the role to 50 Cent, but the decision has come under fire from film fans who claim that the star isn''t a credible actor.

And now, Stallone has promised on his forum, StalloneZone, that he will guide the hip-hop star through the role.

"Please tell the loyal followers to be positive not negative in their feedback. I am not self-destructive. The anger of the casting of 50 Cent is understandable, but not fair,” Contactmusic quoted Stallone as writing to the forum''s administrator.

He added: "A player is only as good as his coach. If a man can communicate in one medium, he can communicate in another if his strengths are brought out and he has the support of well-wishers. So, trust me, the change of Forest Whitaker to 50 Cent AKA Curtis Jackson is a good one." (ANI)
