3. Independence Day (1996)
Independence Day is a two-and-a-half-hour spectacle. Gigantic, city-sized spaceships hover above key cities all across the world, forcing humanity to band together to repel the alien invaders — but not before we see classic sights of New York, Los Angeles, and even the White House itself being destroyed in spectacular fashion. Smith rose to fame in this part, and for good reason: he's immensely engaging as hotshot pilot Captain Hiller, trading fun, light barbs with Jeff Goldblum's David Levinson and dead aliens alike.
4. I, Robot (2004 film)
I, Robot begins with a fascinating premise: in a future where personal robots are becoming commonplace, a major roboticist appears to commit suicide and leaves an alarming message for robot-hating detective Detective Spooner, played by Smith at the peak of his action-hero powers. However, don't anticipate a faithful version of Isaac Asimov's Three Laws of Robotics; aside from an homage to the author's Three Laws of Robotics, it bears no relation to the book of the same name.
