" it will be a serious but entertaining movie that deals with the most interesting and powerful person of the 19th century within an imaginary scenario that he was also an ax-wielding vampire hunter."

Nine Inch Nails star Trent Reznor has pulled out of work on the movie adaptation of quirky bestseller Abraham Lincoln: Vampire Hunter.

The rocker, whose The Social Network score won him an Oscar last month (Feb11), was said to have signed up to compose the music for the dark drama and agreed to appear onscreen in the film.

But he's now revealed to fans he is no longer involved with the project.

In a post on his blog, he writes, "As it turns out, I WON'T be working on (acting or scoring) ALVH after all. There's no juicy story here, it's just that when the news mysteriously leaked out about my involvement I hadn't made up my mind completely, because various aspects of the project were changing.

"I felt the need to say something earlier this week because my inbox was filling up with speculation, and at that moment I thought I would be doing it. Confused yet? Apparently I am. Bottom line, I wish them the best with the film and I'm sure it will still be great."
