What was the name of the 1995 high-tech thriller film which starred Sandra Bullock?

In the mid-1990s, as the internet was rapidly moving from a niche tool to a household phenomenon, Hollywood capitalized on the public's anxieties with a paranoia-fueled thriller. The film, released in 1995, starred a then-peaking Sandra Bullock as Angela Bennett, a reclusive computer systems analyst who works remotely. Her quiet life is shattered when she stumbles upon a dangerous conspiracy hidden on a floppy disk, leading to her digital identity being completely erased and replaced with that of a wanted criminal.

The movie is a fascinating time capsule of the early internet era. It prominently features the technology of the day, including dial-up modems, clunky user interfaces, and the then-novel concept of ordering a pizza online. It was one of the first major films to place the "information superhighway" at the absolute center of its plot, exploring fears of identity theft and the loss of privacy in a world becoming increasingly interconnected.

While the specific technology depicted is now comically outdated, the film's central themes have proven to be remarkably prescient. The fears it explored about data security, digital surveillance, and the vulnerability of having one's entire life stored on computer networks are more relevant today than ever before, making the film both a nostalgic thriller and a surprisingly accurate prediction of modern anxieties.
