Ewan McGregor
Ewan McGregor was another actor who was considered for “Casino Royale,” but he ultimately didn’t seem too interested in the role. This makes sense, considering that in 2005, McGregor was just wrapping up his decade-long stint as Obi-Wan Kenobi in the “Star Wars” prequels. McGregor later stated that he thinks it might have been fun to play Bond, but that he wasn’t interested in lengthy filming shoots and “a massive amount of publicity” once the film released.
