Chain Reaction is a 1996 Science Fiction Thriller film directed by Andrew Davis, starring Keanu Reeves, Rachel Weisz, Morgan Freeman, Brian Cox, Fred Ward, and Kevin Dunn.Eddie Kasalivich (Reeves) is a machinist working at a laboratory researching a new hydrogen power source involving a laser beam and sound waves to induce sonoluminescence. When he returns to the lab after the first stable test, he finds his boss murdered and the place about to explode. He and his coworker Dr. Lily Sinclair (Weisz) are framed for the explosion and have to run from the authorities while trying to clear their names.Not to be confused with the game show that involved a chain of words or with the 1980 Australian film The Chain Reaction.
This film provides examples of:
- Artistic License – Physics: Simply burning hydrogen extracted from water would result in a net loss of energy, since breaking those molecular bonds would require more energy than would be gained from the reaction. If it were some sort of fusion reaction, it would make more sense.
- Can't Stop the Signal: The good guy releases to the world the details of the machine allowing production of functionally unlimited energy by faxing it to news offices everywhere.
- Clear My Name: Eddie and Lily are trying to clear their names after being framed.
- Follow the Leader: The film retreads much of the structure and a number of elements from the director's previous hit film, The Fugitive, down to the lead character being framed for a murder and on the run from reasonable agents who eventually figure out he is innocent.
- Frameup: Eddie, Lily, and Chen are framed as agents for China attempting to steal the hydrogen technology. It's so blatantly transparent that the FBI decides about halfway through the film that they're probably innocent and start working off that assumption.
- Gas Cylinder Rocket: Invoked. During the climax, Eddie uses an axe to chop the valve off a tank of hydrogen gas to shove open a safety door so he and Dr. Sinclair can escape. He wraps the axe in cloth to keep it from igniting the gas.
- Information Wants to Be Free: The researchers wanted to make the technique available to the world for free. The Big Bad didn't, justifying himself with the economic instability this would supposedly cause.
- Orgy of Evidence: After Eddie witnesses the sabotage when he wasn't supposed to, Lyman quickly frames him, Lily, and Chen with some hastily planted evidence pointing at the Chinese. The FBI eventually realize that something is amiss.
- Outrun the Fireball:
- Eddie arrives at the laboratory to find his boss murdered and the equipment rigged to blow up. Unable to stop the chain reaction, he straddles his bike and speeds away from the lab. When the equipment finally overloads, it explodes in a very large fireball, almost akin to a small nuclear blast. Eddie manages to Outrun the Fireball just barely; the back of his bike is actually lifted by the shockwave (but the forward wheel somehow remains on the ground).
- Happens again in the climax, this time heading up as the second reactor is about to blow. The fireball catches him and Lily this time, but fortunately it just flings the lift they were using out of the hole without harming them.
- Reasonable Authority Figure: Interestingly, for a villain, Paul is this. He constantly tries to be helpful to Eddie without exposing himself as one of the Big Bad Ensemble, and absolutely loathes Lyman because he firmly believes Murder Is the Best Solution for anything, and no amount of chewing out will make him stop.
- Stupid Evil: Lyman keeps stepping on Paul's toes to get to Eddie and Lily, even though they trusted Paul and would have come in so long as he guaranteed their protection. Lyman even has the nerve to blame Paul for this. Paul eventually kills him, as their superiors had deemed him a liability.
- You Have Outlived Your Usefulness: Lyman intends to kill Chen, Lily, and Eddie once he has the perfected technology. Idiotically, he makes it perfectly clear this will be the end result of their work once he's kidnapped them, giving them no incentive to play along.
