AceShowbiz - Rami Malek was "concerned" about his "Papillon" co-star Charlie Hunnam's weight loss for their new movie.
The "Sons of Anarchy" star plays a prisoner on a remote island, attempting to escape, in the remake of the Steve McQueen and Dustin Hoffman movie - and to achieve his gaunt look he shed around 35 pounds (16 kilograms).
"I did this two times in a row," he tells U.S. news show Entertainment Tonight. "I did a film called 'The Lost City of Z' and I lost 40 pounds for that exactly. I went from 185 to 145 exactly. I was down to 145 again for this (role), but I think I probably started at 180 so maybe (I lost), like, 35 pounds."
While Hunnam is proud he was able to stay dedicated to his weight loss goal, "Mr. Robot" star Rami admits it was difficult to see his co-star look so skinny.
"Yeah, how can I not be (worried)," he adds. "I mean it's a very intense experience as it is. Filmmaking, and this one especially, it's not the glitz and glamour of Hollywood. We weren't out there going back to our trailers every two seconds.
"(We were) just out there sitting in the mud and hanging out and watching Charlie starve. So, I was a bit concerned, but he's alright."
Meanwhile, Charlie, who is known for his muscular physique and shirtless scenes, insists he is not looking to continue to play sex symbol roles.
"It's certainly not intentional and not something that I want to keep doing, but it seems to be a running theme," he says. "I don't know what that's about."
