Known for his movie premiere stunts, actor and comedian Sacha Baron Cohen walked the red carpet for his latest film Grimsby in Los Angeles on 3 March, arriving as new fictional alter-ego Nobby, who declared his support for US presidential candidate Donald Trump's political campaign.

Speaking as beer-drinking football fan Nobby, Baron Cohen, who is known for his satirical characters, took to the podium to make the announcement. In the film – released as The Brothers Grimsby in the US, presumably because not many people stateside would know what or where Grimsby is – Nobby is reunited with his long lost brother, secret agent Sebastian (Mark Strong), and soon finds himself on a world saving mission.

Nobby told the crowd: "I'm here for something much more important than my film. Today I'm announcing my endorsement for Donald Trump for President. It's Trump's rallies that won me over, they are like soccer matches in England, violence, abuse – the only difference is we don't throw the black people out."

Grimsby was released on 24 February in the UK and will be released on 11 March in the US.
