Actor Mark Ruffalo is playing twins in his upcoming release, I Know This Much Is True for which he had to take five weeks off to gain 30 pounds.
Mark is playing identical twins who look completely different, because they’ve lived different lives for 40 years.
The identical twins, named Thomas and Dominick in the film shared stark different lives. Thomas is schizophrenic and has been on years of medication, while Dominick is not.
In order to play the two men, Ruffalo first shot for all his scenes as Dominick for 15 weeks, and then he took a few weeks off and gained 30 pounds, showrunner Derek Cianfrance shared at the TV Critics Association Winter Press Tour on Wednesday, reports eonline.com.
“We didn’t want it to be like I run and throw a wig on and do the same scene in the same day, so we took six weeks off to really separate these two guys. And Thomas is on medication, mood stabilizers, and anti-psychotics. A lot of people put on weight.”
However, those weeks of gaining weight and preparing to play the other — much more troubled brother — were hard for Ruffalo.
“Those five weeks were really kind of lonely,” Ruffalo said, especially as he began studying what Thomas would have been going through and the life he would have been living with his mental illnesses, including hearing voices in his head.
“Putting on the weight for Thomas was really challenging. I didn’t expect it to be,” said Ruffalo.
“I thought I was going to have a fun time doing that, but when you’re force-feeding yourself, some of the romance of food sort of leaves.”
He also felt a responsibility to honestly represent what Thomas was going through.
“It means a lot to me to be honest with that, which means going into that world and getting to know it and getting comfortable with it,” Ruffalo said.
“And that’s challenging, and so that aspect of it was challenging…I was really afraid to play him. I think it’s really an important issue, and I want to tell it as honestly as possible. The responsibility is on me,” added the Avengers: Endgame star who plays Hulk.
