In 1978, Space:1999's two-part story The Bringers of Wonder was compiled into a feature film - Destination Moonbase Alpha! Here's the film's opening titles sequence, including a Star Wars-esque opening text crawl that gets its space terms mixed up, which updates the show's setting to the year 2100, and which features an opening theme by former Manfred Mann guitarist Mike Vickers. | Official Gerry Anderson
