Let's go to comic melissa McCARTHY. I'm a big fan of hers. A big movie opening this weekend. Topping the box off with the movie, "identity thief." The victory at the box office comes just days after comment weight from a big-name film critic. Cecelilia vega has the story. Reporter: This morning, me LESS IS a McCarthy is having the last laugh. Her latest movie just earned the biggest opening so far this year. Stealing the box office this weekend by raking in more than $36 million. ♪ Now, ooh, barracuda ♪ oh. Reporter: That's $10 million more than "bridesmaids's" opening weeken the film comes on the heels of rex reed's scathing review. He delivers blow after blow, calling McCarthy tractor-sized, a humongous creep, and a hippo. 90% of actresses are extremely skinny. You have someone more overweight being successful, it will draw this type of attention. Just because it's not normal. Reporter: Now the critic calling her out is being criticized himself. Eric stonestreet tweeting, turns out, rex reed didn't die sad and alone ten years ago. Nope, he's alive and starving for attention. So let's give him some. Not me! Reporter: While neither reed nor McCarthy are commenting, she said she's never going to be a stick thin starlet. Two kids, 41. There's so many other things to worry about. Reporter: Her real woman appeal has made her one of the most successful actresses in hollywood. That didn't stop reed from calling her a gimmick comedian who has devoted her short career to being obese and obnoxious with equal success. The woman is trying to mess with your mind, you know that. Reporter: She had a leading role in "gilmour girls." And an emmy awar for "mike & molly." It's my first and best pageant ever. Reporter: Perhaps it's ro roseanne barr who used her weight for comic relief who puts it best. Tweeting these words of ENCOURAGEMENT to McCarthy. You're great comedian. Your body is your instrument. You play it expertly. For "good morning america," se veal cecilia vega. I'm going out on a limb. I echo everything eric stonestreet says. She's totally watchable. You can't take your eyes of her. Also totally watchable, cynthia McFadden.
