Jason Biggs, best known for starring in the American teen comedies American Pie, has slammed David Cameron as a "lunatic", while endorsing Boris Johnson as "incredibly likeable".
In an interview with Politics.co.uk, Biggs criticised Cameron's conference speech and saved particular rage for a video taken of Cameron and his wife Samantha going out for a curry in Birmingham.
"I saw that horribly contrived video of him walking down the street in Birmingham with his wife," he told the website.
"It was like: 'Oops, the cameras just caught us, we're going for a date'. Are you kidding me? Is there a person in the UK who believes this?"
Biggs also claimed the prime minister's speech made Cameron seem like a lunatic but appeared to be quite taken by Johnson, who also recently toured America.
"He did all the shows and Letterman. He was incredibly likeable," he said.
The 34-year-old actor, whose political movie Grassroots is set to be released in the UK on 9 November, praised the job Johnson was doing in London and added: "If I voted Tory, I would vote for him."
