"Star Wars" star Ewan McGregor has attacked the penultimate movie in the sci-fi series saying "Episode II: Attack Of The Clones" was "unsatisfactory".

It's not the first time the Scottish actor has criticised the George Lucas-directed series; he had dubbed "Episode I: The Phantom Menace", "disappointing" following its release in 1999, reported the Internet Media Database.

But McGregor, who plays Obi Wan Kenobe, is far happier with the final movie "Episode III: Revenge Of The Sith" which premieres in May.

"The fighting in Episode II was unsatisfactory, I think. I don't think the fight was nearly as good as it should have been and I certainly didn't have as big a crack of the whip as in the first one," McGregor said.

"I made up for it in number three. We fight our asses off in that film."
