"So I think that means I am really locked into doing the The Dark Tower," he kidded. "So it's just very exciting news for us all – maybe, I don't know."
After years of false-starts, the film is finally moving forward, with Idris Elba as the gunslinger and Matthew McConaughey as the man in black.
When asked whether he could confirm his own casting rumors, Paul told PEOPLE "I have no idea. These rumors have come and gone in the past few years. It would be a dream come true, I love that book series. I'm obsessed with The Dark Tower series and with Stephen King."
