NO less than four youngsters at the Yorkshire School of Acting have roles in new film Grimsby.

And this week the young actors got the red carpet treatment at the London premiere of the movie, written by and starring Sacha Baron Cohen.

The young stars are Jonjon Lockwood and Zak Sutcliffe from Bradford, Gabriel Palmer from Leeds and Freddie Crowder, who comes all the way from Grimsby to attend classes at the Bradford-based acting school.

Zak is already a familiar face, after playing the title role in a TV film of Peter Pan, co-starring Hunger Games actor Stanley Tucci and singer Paloma Faith, which was broadcast over Christmas.

Big screen comedy Grimsby is about a British spy forced to team up with his football hooligan brother on an action-packed assignment.

Sacha Baron Cohen walked the red carpet in character as his latest alter ego Nobby, a beer-bellied terminally-unemployed father-of-nine, wearing a polo neck, blue Y-fronts, socks and slippers.

In the film, Nobby tracks down his younger brother in London, after nearly 30 years, unaware that he's an MI6 assassin. After a disastrous reunion which puts them both on the run, they uncover a plot to destroy the world. In order to save humanity, and his brother, Nobby embarks on a global mission and undertakes a complete transformation from lovable idiot to sophisticated secret agent.

Yorkshire School of Acting Principal Matt Zina was at this week's premiere with the youngsters, who play Nobby's sons. "We were put up in a hotel and picked up to go to the premiere," says Matt. "JJ, Zak and Freddie were there slightly earlier as they were performing on the red carpet with Sacha Baron Cohen. The stars, including Isla Fisher and Mark Strong, were out and we all walked together towards the cinema."

Adds Matt: "As this has been a two-year process, they have been through a lot together. Because the film is a 15 certificate, they produced a special version of the film and put on a special showing of it for the kids to watch. It was a wonderful evening, we couldn't believe where we were!

* Grimsby is released next week.
