X2: X-Men United (2003)

In this sequel, Stryker sabotages the government to find the Brain, a tool created by Professor Xavier, and at the same time gets revenge on all mutants, as his son was a student at the school. Meanwhile, Wolverine struggles with his memory loss and tries to remember who Stryker is so he can help stop him. With great special effects and the magic touch of the X-Men franchise, it's a great choice anytime.
