"I know they say never say never, but right now, I can’t imagine it. I don’t want to ruin what Melissa and I had," Bullock said. "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's hesitation seems to stem from her previous sequel experiences, which include the marginally successful "Miss Congeniality 2: Armed and Fabulous," as well as 1997's notorious dud, "Speed 2: Cruise Control."
“If you look back on my illustrious sequel work, nothing has proven successful,” Bullock joked. “A sequel is such a daunting thing, because you don’t want to lose the magic and the charm of the first one.”
Despite Bullock's reservations, "The Heat" screenwriter Katie Dippold is already working on a sequel — so maybe the third time will be the charm for Bullock, who will next be seen in theaters when Alfonso Cuarón space thriller "Gravity" is released on Oct. 4.
