Robert Downey Jr. has accused other Hollywood stars of being too consumed by their own celebrity - calling his superficially-minded peers "zombies".

Downey Jr. claims too many of the current crop of screen stars are more interested in being famous than making great movies.

He tells GQ magazine, "For some people, fame and success is what finishes their thing, because in some twisted way that’s all they ever wanted. I know people like that.

"They’re like zombies. But they’re complete zombies. They’re done, they’re cool, in a very two-dimensional way. They can move anywhere inside the frame and they’re well-lit, and it’s fine."
