Based on the Cartoon Network series and directed by Alex Winter — yes, that Alex Winter — Ben 10 Race Against Time is a great live-action version of a kid-friendly series that you may have slept on.
Ben Tennyson has the power of the Omnitrix, which allows him to transform into a multitude of super-powered different characters (for ten minutes at a time) to protect the galaxy, a job his grandfather (Lee Majors!) has done for decades. But now, Eon wants to destroy our her and use the Hands of Armageddon to open a gateway to his home dimension and unleash war upon our planet.
It turns out that Eon is an alternate reality version of Ben gone wrong, one that has learned how to get past the time limit of the Omnitrix. Only four of the powered forms — Diamondhead, Grey Matter, Heatblast and Wildmutt — show up here, but I really enjoyed getting to see a live-action version of a cartoon that I really dig.
Winter would also direct a sequel, Ben 10: Alien Swarm. And hey — Lee Majors is the perfect actor for Max.
