Star Trek and Stargate are two of the most prolific and beloved science fiction franchises, and it is no surprise that actors would overlap between the two series. Both Star Trek and Stargate had shows running throughout most of the 1990s and early 2000s, and many actors made appearances on both shows. Star Trek and Stargate often borrowed episode titles and even plots from one another. Each Stargate series follows a different team of adventurers as they explore various planets by traveling through a massive Stargate that was discovered in the ruins of Giza.
The Stargate franchise began with the Stargate feature film in 1994 and would continue with three television series and two made-for-television movies. The first of these was Stargate: SG-1 (which concluded with two movies), followed by Stargate: Atlantis, and Stargate: Universe. With ten seasons, SG-1 was the longest-running genre show until the CW's Supernatural claimed that honor with its fifteen seasons. While the Stargate franchise never quite achieved the level of pop culture saturation that Star Trek has, both franchises have a lot in common, including the following twelve actors.
