"The Heat" was a surprise hit this year, and director Paul Feig would agree to a sequel. However, lead star Sandra Bullock would refuse as she has done bad sequels already.

"I'm not doing a sequel to 'The Heat,'" when she was interviewed by The Wrap at the Tuesday premiere of her new film "Gravity." "I've done two sequels. They were horrible. What Melissa and I had was beautiful. We might do another film together. I think we should do a silent film together."

Feig laments the incomparable chemistry Bullock had with Melissa McCarthy: "It would be very hard. They're so great together. Their chemistry is so awesome. I would be very sad if I didn't have both of them back."

The surprise hit of the summer took on such powerhouses like "Man of Steel" and "Despicable Me 2,"  but the R-rated buddy cop comedy racked up nearly $225 million worldwide. Feig thinks he knows why "The Heat" was able to break out of the pack.

"People wanted to have fun this summer and they wanted to see strong women being funny," Feig said. "It's really breaking down the Hollywood prejudice about putting women in lead roles. After 'Bridesmaids' and then this, I feel like we're really breaking down the wall. Look, movies starring women and funny women can make money, so lets make more."

He'll have to do it without the "Gravity" star. It seems like she has made up her mind. The stigma of those two films were a lot to take. The movies "Speed 2: Cruise Control" and "Miss Congeniality 2: Armed and Fabulous," were the low points of her career.

Feig was the director of "Bridesmaids" and wants to advocate comedy movies headlining women. "The Heat" was a step towards that goal.
