Sacha Dhawan says Doctor Who's diverse casting makes it a "landmark show"

The true identity of his role was revealed in the twist ending to series opener Spyfall - Part One, but keeping quiet about his initial casting proved quite the challenge.

Dhawan explained: "It’s actually really difficult and I think the more you’re told not to say something, the more you want to! It’s an amazing feeling, especially being the first British Indian actor to portray the role. I’m really proud and excited for people to see it."

"There was a time when actors like myself, wouldn’t even be considered for a role of this nature. Doctor Who has always been a landmark show, but I feel it’s becoming an even more landmark show due the stories that are being written, and the actors being cast to represent them.

"Yes, I’m a nemesis alien time lord, but that’s only the surface. For me, the role becomes ‘iconic’ because if you look beyond that you’ll see that there’s a much deeper story that’s going on. Once I realised that, I couldn’t feel more proud to be incarnating the character."
