In advance of its release, Keanu Reeves and Sandra Bullock‘s 1994 film Speed was kind of being dismissed as nothing more than a rip-off of Die Hard. After all, the Bruce Willis film had inspired all sorts of variations of the theme of Die Hard, such as on a plane (Air Force One), battleship (Under Siege), airport (Die Hard 2: Die Harder) and, of course, a bus (Speed).

In the film, former LAPD bomb squad expert Howard Payne (Dennis Hopper), rigs a bus — the passengers of which includes Sandra’s Annie — with a bomb that will explode if the speed of the vehicle should drop below 50 miles an hour. It falls to LAPD officer Jack Traven (Keanu) to somehow come up with a way to board that bus and save the passengers without detonating the bomb. What follows is a genuinely suspenseful adventure filled with action, humor and some unbelievable stunt work.

Now here we are all these years later with Speed celebrating its 25th anniversary, and Keanu and Sandra (still) being two of Hollywood’s biggest stars. Keanu, in particular, is pretty hot again thanks to a large degree to the John Wick trilogy, which has captured audience’s imaginations.

To celebrate the enduring success of Speed, what follows is a look at some behind-the-scenes facts about the film that you may not be aware of.
