Oscar winner Dame Helen Mirren insisted on wearing the right shoes to play a cold-blooded killer in the Red sequel.

The Brit revives her expert assassin character Victoria in Red 2 and admits it was her idea to make sure the killer made a fuss about her footwear.

Mirren says, "I love that she loves to kill in formal wear; as long as she's got the right shoes on. The shoes are very, very important.

"There's a scene in the first Red that was completely my idea, where I take a pair of combat boots out of a bag and I say, 'You can't do this kind of job in high-heeled shoes if you're going to be serious about it'."

The Queen star admits she loves playing such a bad girl in the action films: "I love being a bad**s; it's just the best! Fans think it's the Queen doing that and they love the idea of that. To lurch from being the Queen to a bad**s is very cool.

"I'd love to do a superhero movie, where I'm the proper baddie."
