In the 1994 film "Speed," Sandra Bullock plays Annie, the passenger who takes control of the runaway bus.
Annie Porter becomes involved when a city bus is rigged to explode if its speed falls below 50 miles per hour. After the original driver is injured, Annie ends up driving, despite not being a professional bus operator. Her practical judgment and ability to stay calm under pressure make her essential to keeping the passengers alive.
The film pairs Bullock with Keanu Reeves, who plays LAPD officer Jack Traven. Jack boards the bus and tries to stop the bomber's plan, while Annie handles the impossible driving situation. Their chemistry became one of the movie's major strengths and helped establish Bullock as a leading star.
The role went through several changes during development. Annie was originally written as an African American paramedic, and Halle Berry was offered the part before declining it. The character was later reshaped into a passenger and love interest. Bullock auditioned alongside Reeves, helping convince filmmakers that their on-screen partnership worked. The film's antagonist, Howard Payne, is played by Dennis Hopper.
