Two decades ago, director Roland Emmerich and producer Dean Devlin had planned out a trilogy of "Stargate" films with the first hitting cinemas in 1994. It performed well, but the subsequent TV series spin-off, which the pair weren't involved in, lead to the scrapping of further film entries.
Now, with the TV franchise long over, the original film is being rebooted with both Emmerich and Devlin back onboard. Speaking with the Portland Business Journal, Devlin confirms that the pair are actually moving forward with their originally envisioned plan from back in the 1990s rather than starting afresh. He says:
"We did the original Stargate as an independent movie. It was a surprise success. Shortly before the movie came out, the financiers who were frightened the movie might not do well sold the film to MGM. When the film came out, it was a hit and spawned TV shows.
Of all the projects I’ve ever done, Stargate is the only one from the beginning intended to be a trilogy. We always wanted to do parts two and three, but the thinking was they didn’t want to do anything other than the TV series. So literally for 20 years I’ve been chasing this project.
Twenty years later, we can’t really do part two. We have to start over from the beginning. So let's reboot the series, put in all the things we couldn’t the first time, and set it up properly."
