They sure don't make trailers like this anymore. Or even movies, for that matter. I blame the Blue Meanies.
This original theatrical trailer for the Beatles' 1968 psychedelic classic, Yellow Submarine, was released to celebrate the release of the Blu-ray and 4k remastered versions of the film. You can find the Blu-ray version for $22 at Amazon, though the 4k version seems to be vaporware. If you've spotted a copy online, let us know in the discussion below.
