24 star D.B. Woodside has admitted that he wasn't happy with the way his character was written in the most recent season of the show.

The actor joined the Fox terrorist drama for the third season in 2003, playing President David Palmer's brother and White House Chief of Staff, Wayne Palmer. Although he did not appear in season four, he made guest appearances in 2006 for season five and his character became President of the United States in this year's run. However, Woodside was disappointed when he realised that producers were changing Wayne to fit in with his new presidential role.

"I thought a little bit like they were almost giving me a new character at the beginning of this year, simply because he was president," Woodside told IGN.com. "I think that they were probably somewhat nervous, and to be candid, it didn't work.

"And I think that as writers they know that - as an actor, I sure as hell knew that - and that both of us kind of dug an impossible hole that the writers and myself spent a good part of the year trying to climb out of. I think unfortunately, for most of the season, it was… I don't think it was bad, I just think it was disappointing."

Producers have promised that there will be a "major re-creation" of the show when it returns next year, following criticism of season six.
