Michael Fassbender has done a fascinating interview with the Hollywood Reporter. You can read the full article at the link, but here are a few good quotes.

On how he survived years of struggle: “I would say to myself, I’m good enough. That became my mantra.”

ON GOING NUDE, MEETING SEX ADDICTS AND USING YOUTUBE TO HONE HIS CRAFT
Fassbender says what attracted him to the role of Brandon, a sex addict in the Fox Searchlight indie drama Shame– produced by See Saw Films and Alliance–was the chance to explore the desperate search for connection; playing a young Jung in A Dangerous Method allowed him to morph into a historical character. “I was a bit worried that I’d perhaps bitten off more than I could chew,” he says. “But I’m always interested in trying to investigate different personalities. I want to keep myself guessing and keep the fear element alive, so that I don’t get too comfortable.” Jeremy Thomas, a producer on Dangerous Method, says Fassbender who was director David Cronenberg’s first choice to play Jung read the script over and over again, even during production, something Thomas has never seen an actor do. “It’s one of his secret weapons,” he says. Fassbender says he’s grown deft at using YouTube to study accents (his own is Irish) or to watch a grainy interview with an elderly Jung. For Shame, he met with recovering sex addicts: “One man had the same intimacy issues that Brandon had, so it was very helpful to me, and I was very grateful that he opened up.” Additionally, he says there was no time to feel too self-conscious when shooting Shame, says Fassbender. It helped that director Steve McQueen kept the set intimate. “We moved very fast. We shot it in 25 days, so I kind of had to get over it and get on with it,” he says.

THE ACTOR ONCE LIVED WITH REJECTION, A HOLE IN HIS WINDOW
The son of two restaurant owners, Fassbender moved to London at 19 and attended the Drama Centre. “It took me a while to come to grips with how expensive London was. My parents helped me out, but we never had a lot of money,” he says. “So it was very sticky the first three or four years between paying drama school fees and surviving. The first place I lived was a studio I shared with a Brazilian girl. We weren’t seeing each other or anything, but I remember there was a big hole in the window and it was so cold in the winter.” Fassbender’s first acting role of note was in HBO’s Band of Brothers, which aired in 2001. He was confident it would lead to other offers. It didn’t. “I came to Los Angeles and did auditions for television. I made a terrible mess of most of them and I was quite intimidated,” he recalls. “I felt very embarrassed and went back to London. I got British television jobs intermittently between the ages of 23 and 27, but it was very patchy.” Between roles including a Guinness commercial (in which his character swims from Ireland to New York) and a one-off, Agatha Christie’s Poirot, he took odd jobs to survive, unloading trucks or bartending. He even did market research. “I had to call people who had filed complaints about the Royal Mail and see if they were happy with how their grievances were dealt with. Most of the time they weren’t,” he says. All along, he says, “My goal was for acting to become my main income. I would say to myself, ‘I’m good enough.’ That became my mantra.”
