Emily Blunt has revealed one of her biggest fears cockroaches.

In an interview for the May issue of Elle magazine, the actress squirmed as she recalled being overrun by insects on the set of the comedy Arthur Newman, Golf Pro.

Emily was freaked out by the creatures, but insists she wasn't the only one.

"We were filming in this really damp, run-down old house in North Carolina," she said.

"I was sitting with my make-up artist and all of a sudden she went, Ooooooooooah!' I looked around and it was like the sound had cut out everything went into slow motion. It was a cockroach, like, this [she holds her fingers about four inches apart] just sitting right on my shoulder," she squirmed.

Emily also jokes that she fears deportation from the US after squashing bugs with a biography of former president John F. Kennedy. She accepts that Americans might not be pleased with her behaviour.

"The bugs in the south, it's so bad. There was a huge on in my bathroom that I had to squish with a biography of JFK," she confessed.

"I might be deported for saying that. I'll be black-bagged and you'll be Tasered, with your brain erased."

Arthur Newman, Golf Pro, also stars Colin Firth, Phillip Troy Linger and Anne Heche.

It follows two people are who are trying to escape their past by moving into an abandoned house together.
