LOS ANGELES - JUNE 15: Ryan Reynolds at the premiere of Warner BWe’ve all heard how difficult it can be for actors to fully immerse themselves into a role. When Heath Ledger died suddenly after portraying the Joker (before The Dark Knight was even released), Jack Nicholson, who formerly brought the iconic role to the big screen, expressed that taking on such a nasty persona can really take its toll on someone.

It sounds like Ryan Reynolds now understands exactly how that feels.

The Canadian actor had been working on the film Deadpool for years. When it finally wrapped, he says he suffered from a mental collapse.

In GQ magazine’s Men of the Year issue, Reynolds explained: “I felt like I was on some schooner in the middle of a white squall the whole time. It just never stopped. When it finally ended, I had a little bit of a nervous breakdown. I literally had the shakes. I went to go see a doctor because I felt like I was suffering from a neurological problem or something. And every doctor I saw said, ‘You have anxiety.’”

It took 11 years of campaigning and hard work to bring the film to audiences. “And I was banging the loudest drum for Deadpool,” he said. “I wasn’t just trying to open it; I was trying to make a cultural phenomenon.”

Fortunately, the movie was a massive success for both Marvel and Reynolds. The sequel is currently in the works already as the 40-year-old actor, and his wife, Blake Lively, prepare for the arrive of their second child.

It’s always interesting to hear how actors reflect on huge projects. Certainly, a superhero movie is a big undertaking since comic fans will be so critical but it must have been vindicating to have it so well-received.

It sounds a bit like he suffered from what many of us feel on the day after major holidays, such as Christmas (but, of course, on a much larger scale). The build-up is both excruciating and exciting and then when it’s over, there’s this stressfully empty feeling inside. Like something is missing but it’s not.

Either way, it’s interesting. Hopefully, he won’t have any of those issues after making the sequel!
