Emily Blunt and Ewan McGregor Charm the Crowd at Premiere of “Salmon Fishing in Yemen" [SLIDESHOW]

British films are all set, apparently, to re-take the distinction of creating successful romantic comedies.

The newest film in the genre, "Salmon Fishing in the Yemen", stars Emily Blunt and Ewan McGregor and has been directed by Lasse Hallstrom. The scrip has been written by Simon Beaufoy of "Slumdog Millionaire" fame.

The film revolves around a Sheikh in the Middle East trying to bring his favourite pastime of salmon fishing to the deserts. A British fisheries exporter, who believes it is absurd to bring fishing to a land where there is hardly any water, is assigned the mission. However, things change when the Prime Minister's secretary gets involved in the project. She portrays the project as a "goodwill" story for improving Anglo-Arab relations to distract citizens from the Afghanistan war. The cast is then left trying to desperately achieve the impossible.

The star cast includes Amr Waked, Catherine Steadman, Tom Mison, Rachel Stirling, Tom Beard, Jill Baker, Matilda White and Olive Wood. The film was mainly shot in London, Morocco and Scotland.

According to the Daily Mail, Blunt stole all the limelight when the stars arrived for the premiere in London. The actress ignored the rain and weather to debut a rather bizarre new look - cropped back-to-front jacket matching her pencil dress. She stepped on to the sodden red carpet in a blue and black striped frock with a sheer jewelled hemline. The outfit was finished with sky-high black peep-toe Louboutins and Tiffany & Co and wore her hair down.

McGregor, meanwhile, wore black skinny trousers, a jacket and a scarf, with black footwear (that had a rather large white and black striped sole).

Finally, McGregor admitted he had a wonderful time working with Emily.

"She is a great partner to have in a movie. She is a lovely woman, she is funny. She has a wicked sense of humour. There is something very similar about the way we approach our work and we threw ourselves into the scenes. We didn't have a great deal of discussion about what we were going to do before the camera was rolling and I like that the best. The story just grabbed me more than anything. Fred does start off in a very different place than he ends off and that is always very satisfying for an actor," he explained.
