Space Odyssey: Voyage to the Planets, marketed as Voyage to the Planets and Beyond in the United States, is a 2004 two-part fictional documentary created by Impossible Pictures and produced by BBC Worldwide, Discovery Communications and ProSieben. Space Odyssey chronicles a fictional crewed voyage throughout the Solar System, which is used to convey scientific information on spaceflight and on the different planets. The programme was initially announced under the title Walking with Spacemen as an instalment in the Walking with... franchise of documentaries. Though the title was changed before release and its connection to the other Walking with... programmes was removed, it was broadcast under the original title in Canada. The special effects and scientific accuracy of Space Odyssey was praised by critics, though some criticism was leveled at the storylines and drama portions of the programme.
