Sandra Oh has insisted the U.K. is "behind" the U.S. when it comes to diversity behind the scenes in film and TV.

The Killing Eve star spoke with Kerry Washington during an episode of Variety's Actors on Actors: At Home about working on the hit BBC programme, and she confessed she's "totally used to" being the only Asian person on set.

"The U.K. I'm not afraid to say is behind," Sandra shared. "I am not only the only Asian person on set, sometimes it changes - which is very exciting when someone comes on set - but the development of people behind the camera is very slow in the U.K.

"I don't know about the rest of Europe, so sometimes it was a littleā€¦ sometimes it would be me and 75 white people and I have not come from that in my film career, which has been much more independent."

Explaining that her experiences have usually been more diverse, Sandra said: "Mostly working with women and women of colour in the United States it hasn't always been all-white, but being the only Asian person is definitely a familiar place for me.'

"I've got to tell you. Even more than that, I think being the only American on that set (for Killing Eve), in Europe, informed me more than the physicality. I've not even really talked about this, but there is something about constantly feeling like the observer or the outsider."

Sandra's comments echo those recently made by 12 Years a Slave director Steve McQueen, who also insisted the U.K. has a "shameful" lack of diversity in its film industry and lags "far behind" the U.S. in representing ethnic minorities in production.
