Ryan Reynolds

The 46-year-old actor battled insomnia and anxiety while working on and promoting the first 'Deadpool' film.

He told Variety: "I never, ever slept. Or I was sleeping at a perfect right angle - just sitting straight, constantly working at the same time. By the time we were in post [production], we’d been to Comic-Con, and people went crazy for it. The expectations were eating me alive."
