Doctors star on working with twin

The pair have worked together in the past and when asked what it was like, Matt said: "It's great. It's weird as we know each other so well, there are almost no surprises, we know what's coming, which can be a bit disappointing.

"But it's always great fun and it's interesting if you're doing a job as twins, to see how twins are observed and written."

Matt described his and sibling Sam's first joint project, saying: "Johnny Shakespeare actually wasn't supposed to be for twins. I went to the audition and got the job and Jim Cartwright, who wrote and directed, spoke to me after, found out I had a twin and said: 'Brilliant, I'll write Sam into it as well.'

"We were playing these Reggie and Ronnie Kray wannabe gangster drug dealers. It's cool. Jobs for twins are few and far between, but when they do come up they're interesting."
