Indira Varma has said she had no problems with shaving off her long locks to star in new thriller What Remains.
The Luther actress, 40, plays a graphic designer in the four-part series
She said of banishing her flowing dark curls: "Cutting my hair was great fun.
"It's quite rare to have the chance to play something that's so far removed from yourself and I found that exciting.
"You always draw on yourself and what you know, but it was liberating to enter into someone else's psyche and attempt to make her as real as possible."
Indira said of styling her lesbian character, Elaine: "I went on the website Pinterest to look at trendy and sexy lesbians and saw all these brilliant rockabilly styles that I imagined a graphic designer might be into.
"We had ... tattoos done on our necks, chopped my hair off and styled it. Cutting my hair off moved me away from me. It was definitely Elaine."
What Remains, starring David Threlfall, charts the story of a group of neighbours - one of whom is Elaine - who all become suspects when one neighbour, Melissa, is found dead in her south London flat.
:: What Remains starts on BBC One tonight (August 25).
