That’s what Sandra Bullock says it would take for her to suit up for another installment of her hit buddy cop comedy, costarring Melissa McCarthy, which has grossed $130 million and sparked a groundswell of sequel rumors. “I know they say never say never, but right now, I can’t imagine it,” Bullock tells EW. “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.”

The Heat screenwriter Katie Dippold is reportedly already at work on a second chapter of the cop comedy, according to director Paul Feig — but Bullock says she learned a lesson about follow-ups after 2005’s Miss Congeniality 2: Armed and Fabulous and 1997’s Speed 2: Cruise Control, which both disappointed at the box office. “If you look back on my illustrious sequel work [laughs] nothing has proven successful,” says the Oscar winner, who who will be back in theaters Oct. 4 as an astronaut in the Alfonso Cuarón-directed space thriller Gravity. “A sequel is such a daunting thing, because you don’t want to lose the magic and the charm of the first one.”
