Oscar Issac opened up about his body of work, highlighting some of his most cherished roles during an interview with GQ. nHe detailed some of his favorite work including Ex Machina, A Most Violent Year, and most famously his role in the Star Wars universe. His latest offering, however, may have been the least pleasant for the actor.

Apocalypse, that was excruciating. I didn’t know when I said yes that that was what was going to be happening. That I was going to be encased in glue, latex, and a 40-pound suit—that I had to wear a cooling mechanism at all times. I couldn’t move my head, ever.”

Being in character posed physical challenges that made his experience anti-social, isolating him from the film's all-star cast featuring James McAvoy, Michael Fassbender, Jennifer Lawrence and others.

“I couldn’t move my head. And I had to sit on a specially designed saddle, because that’s the only thing I could really sit on, and I would be rolled into a cooling tent in-between takes. And so I just wouldn’t ever talk to anybody, and I was just gonna be sitting and I couldn’t really move, and like, sweating inside the mask and the helmet. And then getting it off was the worst part, because they just had to kind of scrape it off for hours and hours. So, that was X-Men: Apocalypse.”
