Actress Uma Thurman could have appeared in Peter Jackson's The Lord of the Rings series, as she was reportedly offered the role of Eowyn. Appearing on The Late Show With Stephen Colbert last night, Thurman discussed passing on the role, saying it was a huge personal regret.

　　"It was a very long time ago. I do consider it one of the worst decisions I've ever made," she said.

　　So why didn't she take the part? Thurman explained that she had just given birth to her first child and was feeling "a little house-bound" at the time.

　　The three Lord of the Rings movies were filmed simultaneously in New Zealand in the late '90s and early 2000. Some of the actors lived in the country for years during filming. It understandably sounds like Thurman, with her newborn child, was not sure if packing up her life and moving to New Zealand was the right choice for her family.

　　But looking back on it now, Thurman said it was definitely a regret to pass on the role.

　　Colbert, a huge Lord of the Rings fan himself, joked that he would have played Eowyn if the role was offered to him. The role went to Mirando Otto, who played the character in The Two Towers and Return of the King.

　　As with other big-time movies, there are a lot of interesting stories around casting for Jackson's The Lord of the Rings trilogy. Daniel Day-Lewis, Russell Crowe, and Nicolas Cage turned down the role of Aragorn, while Sean Connery said no to playing Gandalf. Jake Gyllenhaal auditioned for Frodo.
