Directed by Paul Feig and written by Katie Dippold, the film sees McCarthy's foul-mouthed, hot-tempered cop and Sandra Bullock's uptight FBI agent teaming up to take down a Russian mobster.
Asked at a recent New York press conference if she regards her character as someone for law enforcement personnel to emulate, McCarthy exclaimed, "I hope not!
"'The Heat' is actually just a training video for policewomen," the 43-year-old Plainfield, Ill., native joked with reporters. "No, I have a lot of police in my family and, no, I think we both tried to, in the handling of the weapons, stay good at our jobs and just be train wrecks in our personal lives as the characters, but, no, I hope not!"
Asked if she ever got injured while filming some of the movie's more physical scenes, McCarthy quipped, "Yes, horribly."
"I'm an idiot. Every time, I'm like: 'I'll do it. I'll go over the fence.' There was a stunt woman who took the fall. I just really enjoy the process [and do as much as I can] until the next day when I'm like, 'Go get me a chiropractor.' I love to see how physical I can be. I find it really fun. I'll probably pay for that when I'm 100 and can't stand up straight," McCarthy said.
The star of the hit movies "Bridesmaids," "This is 40" and "Identity Thief," as well as TV's "Gilmore Girls" and "Mike & Molly," said she and Bullock became fast friends on the set of "The Heat," in part because they are both mothers of small children.
"We just kind of hit it off right away from the first time we talked," she recalled. "I think we have similar humors and I think it is a bonding thing to both have children around the same age and I think we kind of think alike and have weird, similar hobbies and, luckily, it just made the whole thing fun. We got along so well that I felt OK saying horrible things to her, if that makes any sense."
So, given how much fun "The Heat" was to make, is there any possibility of a sequel?
"I'll basically show up. If it's this whole group, if it's a play in a backyard, I'll go do it," McCarthy vowed.
"The Heat" is now on DVD and Blu-ray.
