If an actress wants to be known as something other than "that fat actress" or to be considered for roles other than what boils down to Female Chris Farley roles in which morbid obesity and slovenliness are the punchline, perhaps that actress should stop accepting roles like this:
I mean, jesus christ. Have a tiny bit of self-respect. You're rich. You would think that, like I argued long ago regarding Chris Tucker's repeated choice to play roles that are essentially just black stereotypes, you have enough fucking money at some point that you could say "No, I'm not doing that" without any negative career repercussions. Even McCarthy supporters (not being in the target audience of her films, I know/care very little about her) are begging you to cut this shit out.
Oh and here's the kicker: the film advertised in the above trailer was written by McCarthy's husband. If ever there was an opportunity to create a role that was comedic but not completely, soul-crushingly degrading this would seem to be it.
"Honey, I'm sick of playing fat slobs."
"That makes sense, how about we do a project together where the humor is not based on you being a fat slob?"
Being an actor is hard and being an actress is harder. I always, always look the other way if some struggling young performer takes a what-the-fuck role in order to pay the bills and break into the industry. But once these people are established, rich, and successful there is just no excuse. Peter Dinklage may have played an elf in 2002 when he was a nobody, but he appears to have enough self-worth to turn down the leprechaun roles now that he is a star. There's no reason that rich-ass Melissa McCarthy can't turn down a movie or two that embarrasses and exploits her. Instead, she and her husband are teaming up to write and cash in on even more lowest common denominator Fat Slob vehicles. She has nobody but herself to blame at this point and anyone who feels sorry for her is being conned. As another reviewer said, "She's allowed herself to get typecast in the worst way, and Tammy is the nail in that coffin." The "struggling artist who needs to pay the bills" excuse expired long ago. If you choose to continue doing these Fatsploitation roles, they will keep being offered. If you don't want to, try saying no until something better comes along. Unlike most people, Melissa McCarthy can actually afford to do that.
