Sacha Baron Cohen walks Grimsby red carpet in his undies

SACHA Baron Cohen has made a special eye-catching appearance on the red carpet for the London premiere of his new film Grimsby.

SACHA Baron Cohen has made a special eye-catching appearance on the red carpet for the London premiere of his new film Grimsby.

Dressed in character as protagonist Nobby Grimsby, the 44-year-old braved the cold weather by dressing down.

In place of a smart suit or a tuxedo, he instead wore a polo neck, socks, sandals and underwear.

Sporting a paunch and a beer can, the look was rounded off with sideburns and the type of haircut that invited comparisons to rocker brothers Noel and Liam Gallagher from Oasis.

Actor Sacha Baron Cohen chows down on some takeaway with wife Isla Fisher.

Cohen, creator of Borat, Bruno and Ali G, plays a perpetually unemployed, but fun-loving football fan in Grimsby.

Sacha will be joined on the red carpet by his Australian wife and co-star Isla Fisher, as well as co-star Mark Strong and director Louis Leterrier.

The film follows father-of-nine Nobby, from Grimsby in north Lincolnshire, who is happily settled with his girlfriend (Rebel Wilson).

Baron Cohen and Fisher have three children together.

But the one thing missing in his life is his younger brother Sebastian (played by Strong), from whom he was separated as a child.

After 28 years, Nobby tracks his sibling down — but is unaware he is now an MI6 assassin.

As the film unfolds, the brothers must unite to defeat a plot to destroy the world.

The actor and comedian has made a habit of appearing on the red carpet in character.

Cohen is also the creator of Borat, Bruno and Ali G.

In 2012, Cohen arrived at the Oscars as Admiral General Aladeen from his movie The Dictator, flanked by uniformed female bodyguards and carrying an urn which he claimed was filled with the ashes of former North Korean leader Kim Jong-il (they were, in fact, flour). He was escorted off the red carpet after pouring the urn over host Ryan Seacrest.

Fans were also treated to the spectacle of the actor as flamboyant fashion critic Bruno in 2009.

Bruno wore tiny leather shorts and a bearskin cap for the London premiere while for the Austrian premiere he donned glittery lederhosen — and in California, a tight, revealing military outfit. For the London premiere of Borat, Sacha arrived in a cart led by a mule, filled with Kazakhstan “natives”.

Australian actress Isla Fisher and Sacha Baron Cohen have been married since 2010.
