Sandra Bullock doesn’t think the movie industry is "brave enough" to make a third ‘Speed’ film.

The 60-year-old actress starred opposite Keanu Reeves in the 1994 action flick - as well as returning with Jason Patric for its derided sequel ‘Speed 2: Cruise Control’ - though has now admitted the chances of director Jan De Bont being given the opportunity to helm another bombastic instalment in the series are slim-to-none.

Appearing alongside Reeves and de Bont at a Q+A session during a 30th-anniversary screening of the movie, Bullock said: "The geriatric version. It won’t be fast.

"All these things happened because the crazy man [de Bont] in the greenish jacket over there. He’s so soft and gentle today and I’m like, ‘That’s not the man I remember.’ But he’s the man who put the energy and the idea together, knew what the audience wanted and demanded it from everyone and everyone stepped up to play it.

"So what would that movie be that would make Jan’s brain and brilliance happy? It would require a lot from everybody.

"I don’t know if we’re in an industry anymore that’s willing to tolerate it and be brave enough to do it.

"Maybe I could be wrong … If he can’t make [what he has in his mind] for the audience, then he’s failed it felt like. I don’t know what we could do that would be good enough for the audience."

While ‘The Proposal’ star doubts a third ‘Speed’ movie will ever happen, Reeves previously revealed he was hoping to return to the franchise in the future.

During an appearance on the ’50 MPH’ podcast, the ‘John Wick’ actor said: "I mean, you know - we'd freakin’ knock it out of the park."

‘The Matrix’ icon added there was a "siren call" attracting him to another ‘Speed’ flick, and emphasised that he was desperate to work with Bullock again after they last shared the screen in 2006 for the romance picture ‘The Lake House’.
