Tremors celebrates its 30th anniversary this year, and Universal Pictures is kicking up a storm to celebrate the occasion. There’s a new direct-to-VOD sequel on the way in the form of Tremors: Shrieker Island and a 30-minute documentary, which the studio made available free to watch online now. The documentary, titled Tremors: Making Perfection, features Valentine McKee himself, Kevin Bacon, looking back on the horror comedy cult classic.
