50 Cent is accusing Hollywood of double standards after seeing the new James Bond holding a gun in posters for Casino Royale - a year after billboards of him sporting a weapon caused a furore.

The rapper - real name Curtis Jackson - is appalled by the fact no one has raised a fuss about Daniel Craig's gun-toting posters when he was castigated for posing with a weapon in billboards for movie Get Rich Or Die Tryin'.

He says, "Get Rich Or Die Tryin' comes out and they want to protest because they see a gun in my hand but James Bond comes out or Mr + Mrs Smith will come out with guns and it's acceptable.

"You can see any kind of gun there is to see on the covers of films. You can go in Blockbuster and see every gun that was ever made."

The rap star calls for one universal ruling about weapons in movie posters - and he'll accept whatever the Hollywood film police decide.

He adds, "Let's not start with 50 Cent and stop with 50 Cent. Let's do it everywhere else and make it unacceptable period. I would gladly join the rest of entertainment if we get there."
