Emily Blunt fears her voice will be dubbed in the new Wolf Man movie as she screams like a man.

The Devil Wears Prada actress stars as the love interest in the remake of the classic 1941 horror movie Wolf Man. However, she admits had to resort to "heavy breathing" when scared as her screams weren't good enough.

She told Empire, "I'm not a great screamer. I don't have a good upper range. I'm sure they're going to have to dub me with someone who has better lungs - or more feminine lungs, at least! I just did a lot of gasping and heavy breathing, which might have to do."

Benicio Del Toro (pic) also stars in the remake, which is directed by Jumanji's Joe Johnston.
