The 48-year-old actor - who can be seen in BBC One's new drama Blackout - claimed that some actors still have a "snobbishness" about working in TV.

"Some film actors... won't do television - which is great!" he told The Guardian. "I've done feature films, but the best scripts I've ever had have been in television."
Eccleston last appeared on the big screen in 2009 film G.I. Joe: The Rise of Cobra, while his recent TV credits include BBC Two drama The Shadow Line and an adaptation of The Borrowers.
"When you're writing for film, you've got a wider canvas and you can concentrate on the visuals," he suggested. "With television, you really can't get away with that much."
Blackout begins on Monday at 9pm on BBC One.
