Sacha Gervasi’s biopic, Hitchcock, hits screens early next year with Anthony Hopkins starring as the highly acclaimed director.

Scarlett Johansson takes on the role of screen siren Janet Leigh and a new clip released online this week shows both her and Hitchcock discussing how he plans to film that now infamous shower scene. Janet's a bit worried about flashing the flesh and getting violent but Alfred assures her that all will be well! His wife, Alma (Helen Mirren) isn't convinced.

We wonder if ScarJo is one of those actresses who stays in character 24/7? Doubt the neighbours would appreciate the screaming in the shower! Hitchcock is in cinemas from February 2013.
