No, not fat actors. God forbid. Making thin actors gain weight is the sign of true authenticity.
Did you really need to make Jared Leto so upset having him gain weight for a movie about John Lennon's murder? Is it that hard to find a fat actor who looks like Mark David Chapman? Hell, I'm a fat actor who looks like Mark David Chapman. There must be thousands of Was the awe-inspiring star power of Jared frickin' Leto that important? He's Jared Leto. One of those names you recognize, but ultimately can't place in the pantheon of boring and unsuccessful and increasingly not even young actors. Unless you were REALLY into Jordan Catalano, he's already interchangable.
Leto is now going on a media tour complaining about how hard it was to be fat. Poor little Jared was too fat to walk. I'm serious. He gained 60 pounds and suddenly he needs a wheelchair. Well, I must just be Jesus walking on water to get around then because I'm fatter than poor little Jared was. Of course, it might have been that he had gout. Yeah, the idiot gave himself gout, either by rapidly gaining or rapidly losing this weight. Many stories don't even point this out, acting like becoming disabled by gaining 60lbs is just obvious.
Poor little Jared also complains about he'll never be the same again after getting fat, like he's damaged goods. Yeah, because rapidly and intentionally forcing your body to gain weight is such a normal experience. Lets be clear here. You forced your body to gain weight rapidly and then starved yourself to lose 62lbs in time for your next movie role. I don't doubt that you screwed up your body, but it had nothing to do with being fat.
Lets save the next poor little Jared from himself, Hollywood. If a role is for a fat character, try hiring a fat person.
