The 36-year-old star has claimed he was pushed to his limits on the movie set to see what he was capable of, reported Femalefirst.
"Trying to fit the keytar into my schedule of things I had to learn was pretty funny. But we were all being pushed to our limits to see what we were capable of.
"We worked for three months on, for instance, one number that happens at sunset where it starts as a scene, then it becomes a song, and then it's a dance and then it's a scene again and it all happens in one take," Gosling said.
"That idea, just the clever nuance of the way Fred and Ginger's characters were trying to make the best of a bad situation, we tried to subvert that lyrically in our scene. We tried to make the worst out of a good situation," he said.
