Mark Wahlberg is the latest star to lose weight for a movie role. But the star looked almost too skinny on the set of his flick, The Gambler, this week.  The film is a remake of the 1974 movie starring James Caan. Check out a photo of Mark Wahlberg's 2014 weight loss here.

“I'm trying to get as thin as I possibly can,” Mark Wahlberg told Extra last month. “I'm playing a literary professor who also has some serious addiction problems, trying to get ready for that.”

Mark Wahlberg reportedly lost around 40 pounds for his role in The Gambler and hopes to stay around 150 pounds throughout filming. But his dramatic weight loss was not easy.

“Anytime I smell food, I get crazy,” the actor continued. “… My daughter was eating a blueberry scone, and I was going to jack her for it… literally going to rob my almost 4-year-old daughter for the blueberry muffin. It’s getting bad.”

Mark Wahlberg is not the only actor to dramatically lose weight for a film role. Below are four other stars who recently shed the pounds for the big screen.

1)    Matthew McConaughey

Matthew McConaughey reportedly lost 47 pounds for his role as AIDS patient in Dallas Buyers Club. The weight loss paid off, as the actor is one of the frontrunners for the Best Actor Oscar next month.  But there were some unexpected side effects, as well.

“The surprise was how the energy that I lost from the neck down transferred to the neck up,” he told BBC. “I became clinically aware, almost hyper, I needed three hours less sleep a night. I had an amazing amount of energy from the head up. That was something I didn't know was going to happen."

2)    Jake Gyllenhaal

Jake Gyllenhaal revealed his weight loss at the Hollywood Film Awards in October. The actor shed 20 pounds for the upcoming film Nightcrawler.

“I can only approach things from a mental place," Gyllenhaal told E! News. "Like I'm playing a character who's hungry, figuratively and literally, who's driven in ways to do things and succeed at any cost. And I think that defines a generation in a lot of way so I wanted to get their mentally and then have it transform me physically, because I am not one to rely on science as much as I am on just sort of instinct. That's sort of the character."

3)    Chris Hemsworth

Even Thor needs to shed the pounds every now and then. Chris Hemsworth is limiting himself to 500 or 600 calories a day as he loses weight for Heart Of The Sea. The flick tells the real-life story of sailors on a ship struck by a sperm whale. The men floated on a raft for 90 day, and the survivors ultimately resorted to cannibalism.

"I mean, you can consume 600 calories in a milkshake," he told Jimmy Kimmel in November. "So it ends up being a couple of small salads, a couple of small pieces of protein, and that's kind of it and you go to bed hungry. And then you have like a fasting period of 15 hours, like you stop eating completely, and then you have little meals through the day.”

4)    Jason Segel

While the above actors lost weight to portray starving characters, Jason Segel slimmed down for a different reason. The actor wanted to shed some pounds for his role in Sex Tape. The sitcom star plays one half of a couple whose sex tape mysteriously disappears.

"I've just been living healthy, exercising, eating right — no more midnight pizzas," Segel told Us Weekly. "This time when I take my shirt off, I've made a promise to myself, it doesn't have to be funny."
