Kim Cattrall: I loved filming Meet Monica Velour
The actress, who is best known for her role in Sex and the City, plays an ageing porn star in the film, which also stars Dustin Ingram and Brian Dennehy.
In the movie, an awkward teen meets the former adult entertainer, whose career peaked in the 80s, and develops a friendship with the actress.
According to AP, the actress had to put on 20 lb to play the role, which she described as a relief.
"It was like getting rid of the Barbie doll and throwing it out and starting again," she said.
"We were shooting in Detroit, and there's a lot of great bars in Detroit. So I ate and I drank for about six weeks."
The film is set to open in the US in April, while the actress is also expected to star in next year's The Treehouse, alongside Jeremy Irons and Tom Sturridge.
