The actor has starred in X-Men: First Class, A Dangerous Method and Shame this year and will soon appear in director Ridley Scott's sci-fi epic Prometheus.
While promoting Shame, Fassbender joked to The AP that the public might be growing tired of him after such a busy year.
"After Prometheus, I just shut up shop. I'll give myself a break and I think everybody else. It's sort of like Fassbender overload here," the star quipped.
Fassbender also disclosed that his acting inspiration has always come from the late John Cazale, who played Fredo Corleone in The Godfather and an inept robber in Dog Day Afternoon prior to his death from cancer at an early age.
"The unpredictability that he managed to incorporate in his physical life, I was like, 'I need to be doing something like that'," Fassbender said of Cazale. "For me, sometimes I can express much more of an intention with my body and body language than a page of dialogue."
This week, Fassbender revealed that the upcoming Promethus is linked to Alien and teased that fans will see some creatures they are familiar with.
