The 52 year-old, iconic British sci-fi series, ‘Doctor Who’, has cast it’s first ever trans actress.

Trans, lesbian comedian, Bethany Black, has been cast in the ninth run of the hugely successful Doctor Who TV franchise. She announced the news over Facebook, but didn’t give any details about the role except that it was “the gig of a lifetime”.

She wrote on her Facebook page:

“It is genuinely the greatest job I could ever have imagined getting. Everything about it is magical. I’m enjoying every day of filming and cherishing it, because you never know if you’ll ever get to do anything like this again.

“I only hope that I do the role and the show justice, and that you all enjoy it. For me it’s the gig of a lifetime.”

She also joked, “Now to sit back and wait until The Mail realises the BBC have cast an openly trans lesbian in a family show.”

Black got her first big break on the small screen last year, when she was cast as Helen Brears in Russell T. Davies Channel 4 series Cucumber, which premiered in January 2015.
