Stephen Dorff could have "horns" and "wings" in his new movie 'Immortals'.

The 37-year-old actor stars alongside Freida Pinto, Mickey Rourke and Kellan Lutz in the fantasy-action movie, which is being shot in 3-D and he admits the special effects are so technologically advanced he has no idea what his character Stavros or the final film will look like.

He told MTV: "So much of 'Immortals' is going to be done in post production.

"I could end up having horns coming out of my head, and wings. I don't know what's going to happen!"

Dorff has also praised 'Slumdog Millionaire' star Pinto for her performance in the film, which is based on Greek mythology, and admits she was "great" to work with on set.

The actor - who can currently be seen on screens in Sofia Coppola's 'Somewhere' - added: "There's a lot of testosterone in it. But a beautiful girl, Freida Pinto, brings the innocence and femininity to the movie and she's really great. I found her great to work with.

"I had most of my scenes with Freida and this other character Theseus, (played by Henry Cavill)."
