London: English actress Rosamund Pike has revealed that she worked with a dialect coach to perfect her American accent for new film 'Gone Girl'.
The 35-year-old star, who plays Ben Affleck's missing wife in the movie adaptation of Gillian Flynn's thriller novel of the same name, was glad to get help with an American accent she really struggled with, reportedly.
"I had a great dialect coach. You work like you're learning a foreign language. We speak the same language, but we also really don't," she said.
Pike also found the role difficult because she had to gain and lose weight for the film. "I had to fluctuate three times because the weight was scheduled. I had to fluctuate like 12 or 13 pounds. Gain it, lose it, gain it, lose it, gain it, lose it. So I started to think I could do it very healthily... And then I just hit the milkshakes."
