"I know they say never say never, but right now, I can't imagine it," Bullock told EW.com. "I don't want to ruin what Melissa and I had. If a miracle happens where [a script] shows up that really and truly outdid the first and provided an experience that was better than the first one, then I would look at it. But I'm not there."
Bullock cited her lack of luck with the box-office duds "Miss Congeniality 2: Armed and Fabulous" and "Speed 2: Cruise Control" as one reason why she wouldn't leap to star in a sequel to "The Heat."
"If you look back on my illustrious sequel work," she laughed. "Nothing has proven successful. ... A sequel is such a daunting thing because you don't want to lose the magic and the charm of the first one."
