The first trailer for the "Fifty Shades of Grey" movie will be out this week and the original Christian Grey says he can't wait to see the finished product.

Speaking Sunday at a Fox event, Charlie Hunnam said he still believes in the film.

The 34-year-old "Sons of Anarchy" star said he's excited to see it and is "really curious."

Hunnam quit the movie one month after it was announced he had landed the role of the billionaire Grey, a sexual "dominant" who falls for an innocent coed.

He says his schedule didn't give him time to do "Sons" and "Fifty Shades" and recalls the departure as "pretty heartbreaking."

"Fifty Shades" is scheduled to open on Valentine's Day in 2015.
