The Bubble is a 1966 American 3-D science fiction film in color, later re-released under the title Fantastic Invasion of Planet Earth.

The Bubble utilizes many gimmick shots that serve only to showcase the 3-D, which in 1966, after a dozen years' near-total absence from U.S. screens, was once again a novelty interesting in itself.

Scenes of vacant-faced townspeople strolling along the sidewalk in a daze while repeatedly opening and closing umbrellas, prolonged beyond any storytelling necessity, are revisited at intervals.

Much of this gratuitous footage was trimmed out before later re-releases, unburdening the film of roughly twenty minutes of its original nearly two-hour running time.

[6] Unlike the two-camera, two-projector systems used to make and show the 3-D feature films of the 1950s, Space-Vision used a single ordinary movie camera with an external optical attachment that allowed it to simultaneously photograph the left-eye and right-eye views stacked in an "over-and-under" configuration on a single frame of film.

Because each image was only half the standard height, this resulted in a widescreen aspect ratio with roughly the same proportions as CinemaScope.

Functionally identical over-and-under systems, branded with various names, were used for most of the films made during a revival of 3-D that began with the release of Comin' at Ya!

[7] The Bubble, under its original title, was the feature film in a November 2022 episode of the long-running movie-riffing comedy show Mystery Science Theater 3000.
