To clarify a situation created by other reviews, The Phantom Planet is available from several different sources, with some releases offering various extras. As far as I'm aware the only British release comes from Elstree Hill and this DVD has neither Special Features nor has been colourized.
The film itself is strictly low budget with many of its special effects being similarly uninspiring, especially the space craft in flight, accompanied by a script that plods along in spite of an imaginative storyline of an astronaut marooned on an asteroid, being shrunk to six inches tall and fighting off inter-planetary invaders. The virtually unknown Dean Fredericks has the lead role in a short-lived movie career while arguably the best known actors are Coleen Gray, whose start with the major studios soon moved on to "B" movieland, and Francis X. Bushman, coming to the end of a 200 movie career that began back in silent days. In spite of its semi-cult status, viewers wanting their first taste of sci-fi will be much better rewarded with the likes of Forbidden Planet and This Island Earth from the same era.
