Isaac, who appears on the cover of the April issue of Details magazine, explained how he won the title of Nephew of the Year.
According to the 35-year-old star, when he was cast in the upcoming Star Wars: Episode VII - The Force Awakens, his uncle -- a huge Star Wars fan -- absolutely freaked out, and made T-shirts that read, "Estar Guars: Episode VII."
"I gave them to everybody and told J.J. Abrams, who was like, 'Does he wanna be in the movie?'" Isaac said. "He's an extra in a scene with me. How amazing is that?"
Star Wars isn't the only big-budget blockbuster Isaac has on his plate. The Golden Globe-nominated actor is also set to play the villain in the hotly anticipated X-Men: Apocalypse. He's also starring in the upcoming sci-fi drama Ex Machina.
"In order to be a leading actor," Isaac told Details, "everyone has to be an action star, to a certain extent."
This is something 62-year-old Liam Neeson re-discovered when he took on the role of Bryan Mills in the popular Taken series, which changed the course of the star's career and brought him back into mainstream prominence. Neeson recently revealed that he would be quitting action films within the next two years.
In his interview, Isaac also opened up about being compared to Oscar winner Al Pacino, specifically for his performance in A Most Violent Year.
"The fact that I would even be mentioned in the same breath as Pacino, and particularly his performances in The Godfather and Dog Day Afternoon, is insane," Isaac said, downplaying his critical adoration. "I take it all with a grain of salt."
