This was an intriguing pilot for a weekly TV series by Gene Roddenberry.Like the original Star Trek,its first pilot movie failed,so it was given another chance with a second pilot & title change to Planet Earth.The first pilot was pretty good,the second starts out strongly but then runs out of steam.Both pilots are about Dylan Hunt,a contemporary man who,by accident,goes into suspended animation & awakens some 150 years later.In the world he awakes in,Earth had a third World War but is now rebuilding itself.There are cool items in this future world such as a train that travels through underground routes,narc guns,stem devices,etc.Had this gone to a weekly series,it would have followed Hunt & his Team Pax as they explored the world,seek knowledge,& help those less fortunate.It would still make a terrific show now,& with the state-of-the-art CGI visual fx now available,they could make it far more ambitious in scope.

CBS passed on Genesis II to air a series version of Planet Of The Apes. We all know how well that turned out.
Planet Earth was based on one of the stories that was to be used if Genesis II went to series. ABC aired it as a Tuesday "Movie of the Week."

And, Star Trek - The Motion Picture was based on a story idea conceived for Genesis II titled "Robot's Return."
Genesis II was actually quite good, with Trek level writing. Planet Earth suffered a bit, though.

Both Genesis II and Planet Earth are available from Warner's video-on-demand service, Warner Archives. Here's a review from Trekmovie.

I've seen this movie, and I did enjoy it. CBS should have stuck with this.

The name Dylan Hunt was also given to Kevin Sorbo's character on Andromeda. I don't know of that was Gene's thing, or Majel gave the character that name when she got the series going.

Genesis II is available for streaming on a free app titled Movieland TV. As is Roddenberry's 1974 pilot The Questor Tapes, with Robert Foxworth and Mike Farrell. Planet Earth can be streamed on a couple of pay apps, at a cost of about $1.99.

All made by Gene Roddenberry.

Genesis II originally aired in March, 1973. TV Guide had an article with some behind the scenes info about the production. Including a photo of the sub-shuttle being pulled by a pickup truck (a Ford F-150, maybe) with a cable attached to both. I suspect the same "high tech" technique was used to pull the shuttle transporting Kirk to Starfleet Headquarters in Star Trek - The Motion Picture.

Could be.
