Star Wars - Attack of the Clones and Star Wars - Revenge of the Sith would both be infinitely better if a better actor than Hayden Christensen had been cast as Anakin Skywalker.

I really think George Lucas as director was the problem there. Hayden Christiansen isn’t a terrible actor. Neither is Natalie Portman or Ewan McGregor. But all three of them have just terrible, awful line reads in those movies.

Portman’s career took a hit from those movies, though she recovered because she already had a foothold in the industry. McGregor was a well-known actor already, so he wasn’t hurt. Christiansen got demolished.

A bad actor makes themself look bad. A bad director makes every actor look bad.
