Actor Michael Pitt has slammed Hollywood executives for offering stars big salaries to act in movies because he believes the money is really a bribe to encourage actors to engage in global promotion tours.

The LOST star is bemused by actors who believe their payment reflects their acting skills because he is certain the money regards how prepared they are to attend premieres and give television and magazine interviews.

And the star is desperate to be known for his acting and not a phony public persona.

He says, "Movie stars get paid these ridiculous amounts of money - I don't know if they deserve it.

"But I think what they're really getting paid for is not the work but all the other stuff."
