Directed by Andrew Davis (The Fugitive), Chain Reaction is a 1996 sci-fi thriller that combines environmental themes with corporate conspiracy. The film follows Eddie Kasalivich (Keanu Reeves) and Dr. Lily Sinclair (Rachel Weisz), two researchers at the University of Chicago who make a groundbreaking discovery in clean hydrogen energy. Their triumph turns to terror when their lab is destroyed, their mentor is murdered, and they become the prime suspects in a high-stakes government frame-up.

The film's strength lies in its timely premise about the dangers of suppressing green technology for profit, wrapped in a fast-paced chase narrative. Reeves delivers a solid performance as the everyman scientist thrust into a world of covert operations, while Weisz brings intelligence and determination to her role. Morgan Freeman adds gravitas as a mysterious project advisor with ambiguous motives.

While criticized for some plot conveniences, Chain Reaction remains an entertaining thriller with impressive action sequences and Chicago location work that creates a palpable sense of paranoia. The film explores relevant questions about who controls revolutionary technology and what happens when idealistic scientists confront powerful interests. For viewers who enjoy 90s conspiracy thrillers with scientific premises, or fans of Reeves' early action work, Chain Reaction offers solid suspense and remains surprisingly relevant in today's climate-conscious era.
