The Notebook star portrays the lead character in the big screen adaptation of author James Sallis' book of the same name, about a stunt driver who becomes a wanted man after taking part in a heist gone wrong.
And Gosling got so serious about preparing for the part, he became a skilled mechanic, according to co-star Carey Mulligan.
She tells People magazine, "He put together the car he drives in the film himself! And he spent months learning how to be a stunt driver."
And the British actress admits Gosling's research made him a joy to be around on set: "Since he's so prepared, he can have fun with the crew and make you laugh all day long."
