In the supporting interviews for the film, director Morrison commended the research that Pattinson undertook. "Dali and Lorca were very young, still in their late teens and early 20s. No one knew who they were and there are few accounts of what they were like," said Morrison, "but Robert dug up everything he could find."
"It was intimidating but exciting," said Pattinson, "because at that age he was not the Dali that the world knows - the man with the pointed moustache.
"As a kid he was chronically shy but as I read, I've never related to any character more than I did to him. He wrote three autobiographies which completely contradict each other," Pattinson said. "In one of them he says that his mother was abusive. Then in another he says she was the greatest mother in the world and he had the best childhood. There are chapters called Truth and other ones are called Lies and it's just really funny.
"Everyone sees Dali's image as a mask but he was not hiding. It was something he created with great care and he was so much more complex than just this bizarre clown image that he became at the end of his life," said Pattinson. source
