Washington: Naomi Watts has revealed that she’s extremely scared about playing Marilyn Monroe in a new biopic.

The actress is set to play the iconic screen siren in an adaptation of Andrew Dominik’s ``Blonde`` and she admitted the nerves about the part are getting to her.

"It’s a huge pressure. We all feel we know her. I’m very, very scared about that," Contactmusic quoted her as saying.
