Keanu Reeves was in charge of Sandra Bullock’s skirt during ‘Speed’ stunt

Keanu Reeves made sure Sandra Bullock didn’t have a Marilyn moment on the set of Speed.

At a special 30th-anniversary screening and Q&A alongside Reeves and director Jan de Bont held in Hollywood earlier this week, Bullock looked back on filming the memorable LAX airport scene in which she and Reeves evacuated the bomb-rigged bus. The action-packed moment saw the two escape under the moving bus by using a floor hatch as a makeshift sled and sliding to safety.

“I had this dress that was very light and I had a bodysuit underneath, and when we started rehearsing I noticed that the velocity of air would shoot the skirt over my head,” Bullock recalled. “So Keanu’s job for me, which was the most important thing, was to [place his] hand in a way where the skirt doesn’t fly over my head.”

She continued, “So not only did he have to do the stunt [and] to keep me safe, he had to keep my integrity intact, keeping things that didn’t need to be seen on a 17-foot screen.”

Bullock also joked about why she was cast in the high-octane thriller at a time when she was still a Hollywood newbie. “Because if you killed me, I wasn’t a big actor at the time,” she quipped. “It would’ve been ‘Actor dies in stunt in a Keanu Reeves movie.'”

Staged as part of this year’s Beyond Fest, the reunion marked the first time de Bont and his two stars shared the stage to discuss the film since its release. The 1994 blockbuster follows Reeves’ Los Angeles police officer Jack Traven as he races against the clock to prevent a city bus full of passengers, including Bullock’s spunky Annie, from blowing up after it’s rigged with a bomb by vengeful extortionist Howard Payne (the late Dennis Hopper).

At the screening, de Bont marveled at the enduring chemistry between his stars. “When I saw the movie here [tonight], I’ve never been so proud of those two actors,” he said. “What they did for me — quite often unnatural to them what they had to do — is just unbelievable. The relationship that these two created together is absolutely amazing. Seeing them back on the screen tonight, it was so realistic. They were absolutely perfect. All the emotions were right, all the laughing was right, all the smiling, the little smooching. It was really, really cool. I had to tell them how great they both were.”
