London: Actor Paul Rudd says he became a "miserable" company for family and friends for a year as he was preparing to portray the Marvel Superhero "Ant-man".
The 46-year-old actor said he completely changed his lifestyle so that he could fit in the part of conman Scott Lang and his titular alter-ego in "Ant-man", reported Contactmusic.
"I didn't do anything fun for a year. I ate no carbs or sugar, I worked out. I basically made health and fitness the focus of my day, for a long time.
"I would work out with a trainer; I worked with a guy who was teaching me tumbling, how to do flips, things like that. I was eating a lot of protein and vegetables, and I was eating at very specific times of the day. I didn't drink any alcohol. And I was miserable to be around for about a year," he said.
But the actor confessed that he soon started enjoying his new healthy lifestyle.
"I woke up very early in the morning, I felt really good, I had lots of energy and it helped me also just get into the mind-set of this character. I figured if I'm in really good shape, I will feel like less of an impostor in the role," Rudd said.
