Ben 10: Secret of the Omnitrix (2007)

Ben 10: Secret of the Omnitrix is a 2007 American made-for-TV animated science fiction film based on the animated television series Ben 10. The film also serves as the fifth, sixth, and seventh episodes of the series' fourth, and final, season. It aired on August 10, 2007, in the United States and on October 22, 2007, in the UK. During the week-long special "Ben 10 Week" in April 2008 on Cartoon Network, it was revealed that this movie serves as the official finale to the series, canonically, even though it debuted months before the last six episodes of the series were aired. It was released to DVD on May 20, 2008 exclusively at Walmart stores. However, neither of the alternate versions were on the disc, but the fourth season DVD contains all four versions, plus the pop up trivia version.
