Welcome to What Was Your Planet Called?, a fanlisting for Jason Nesmith/Commander Peter Quincy Taggart, the character played by Tim Allen in the 1999 film Galaxy Quest.

Once the star of a popular sci-fi television series, washed-up actor Jason Nesmith has been left feeding off his past glories on the convention circuit…until the good-natured but naïve Thermians mistake the series cast for real space explorers. When they are recruited to face the evil alien Sarris, Jason welcomes the exploit as the role of a lifetime—but as the humans find themselves over their heads in a life-and-death battle, Jason is forced to discover his true courage and leadership.
