The movie Crazy, Stupid, Love seems to be shot primarily in California. But still Ryan Gosling has this weird accent. What would you call this accent? Is there a specific reason for this accent?
That's called phony accent.
Ryan Gosling told to W magazine about his infamously slurry speech,
"As a kid I decided that a Canadian accent doesn't sound tough. I thought guys should sound like Marlon Brando. So now I have a phony accent that I can't shake, so it's not phony anymore. I'm going for the Madonna thing, the Lady Gaga thing--a phony accent that becomes your trademark."
