X2: X-Men United

William Stryker's (Brian Cox's) son Jason (Michael Reid) was an illusion-projecting mutant that Professor Xavier (Patrick Stewart) was unable to help or "tame", and the boy caused Stryker's other family members to die. Stryker also had a hand in 'installing' Wolverine's (Hugh Jackman's) Adamantine skeleton. The mind-control substance comes from the lobotomized Jason Stryker's spinal fluid. Stryker's plan is to cause paranoia and fear of mutants, starting with Nightcrawler's (Alan Cumming's) attack on the President, hoping it will lead to registration, confinement, and ultimately "Death by Cerebro" of all mutants using a mind-controlled Xavier; as revenge for his family's bad fortunes. His attempt is stopped, along with Magneto's attempt to kill all humans by switching Cerebro's "polarity". In the end, Wolverine (Hugh Jackman) kills Lady Deathstrike (Kelly Hu), Magneto (Ian McKellen) kills Stryker by wrapping him with chains and letting him drown, and Pyro (Aaron Stanford) becomes power-hungry and joins Magneto's Brotherhood of Mutants. Jean Grey (Famke Janssen) saves everyone in the jet, but "appears" to drown when the dam that was concealing the lab finally breaks (Can you say 'Phoenix Saga?')
