Actor has refused to let screenwriter Aaron Sorkin's criticism sour his experience on the set of his upcoming Steve Jobs biopic.
Sorkin's negative comments about the actor were leaked online as part of the Sony hacking scandal.
Fassbender found himself caught up in the hacking controversy last year after an email exchange between Sorkin and producer Scott Rudin surfaced online, in which they discussed possible casting options for the Jobs movie.
In one message, Sorkin made it clear he didn't care for Fassbender as he had never even heard of the actor, declaring, "I don't know who Michael Fassbender is and the rest of the world isn't going to care."

He eventually came round to the idea of casting the German-Irish star as late Apple genius Jobs, stating, "He's a great actor whose time has come."
Fassbender recently finished shooting the biopic with director Danny Boyle, and he admits he didn't let the Sorkin swipe get to him as he just wanted to do a good job.
"It's whatever. People have opinions. The Internet is the Internet. I have a job to do, so I just get on with that."
In December, Cyber criminals hacked into Sony Pictures' database following the release of Seth Rogen's The Interview, a comedy which centres on the assassination of North Korean leader Kim Jong-Un.
