Although John Agar is the nominal star of this unsold TV pilot the bulk of the exposition goes to Harry Townes - who like most of the cast is more familiar for his work in television than in films - although the real stars are easily the special effects crew who created the wheel in space for 'Conquest of Space' which Paramount are here trying to squeeze a bit more money out of under the direction of future 'Star Trek' director Joseph Pevney.
The virtue of 'Destination Space' is that it's much sorter, it's vice being that it's in black & white rather than colour. Most of the plot actually takes place on Earth where the endless haggling with politicians over costs is probably the most accurate prediction that it makes.
