Rupert Everett blames endorsement deals for making Hollywood stars "boring" as celebrities representing huge brands must always be on their best behavior.

The My Best Friend's Wedding star insists A-listers who are company spokesmodels can no longer speak their minds or act outrageously, and he longs for the days when stars were themselves.

He tells Britain's Glamour magazine, "Maybe they (stars) were boring anyway. I came out of a world of people like Elizabeth Taylor, Richard Burton, and Faye Dunaway. You saw them drunk, you saw their double chins, got a feeling for who they were.

"Real stars are humans, not robots. That changed with endorsements. If you're the face of Revlon, you can't afford to have much of a personality."

Rupert Everett admits he was urged to tone down his scandalous antics at the start of his career, adding, "They did (try to manage my behavior) but it was already too late... In the '80s, you could still be outrageous, but all that changed in the '90s. I didn't realize at the time, or I'd probably have changed too."
