"I'm Liz Parker and five days ago I died. But then the really amazing thing happened. I came to life."

And with that iconic introduction on October 6, 1999, one of the most fervent online fanbases was formed. Roswell premiered 20 years ago, introducing viewers to Liz (Shiri Appleby), an average high school girl whose life is saved and changed forever when she is saved by Max Evans (Jason Behr), her classmate who also happens to be an alien, along with his sister Isabel (Katherine Heigl) and troubled best friend Michael (Brendan Fehr), delivering a new sci-fi take on the teen drama genre; teen alienation had never before been so literal. 

While it never attracted a huge audience, Roswell, which was based on the book series Roswell High by Melinda Metz and came from Parenthood and Friday Night Lights' Jason Katims, became one of the first shows to develop a passionate and engaged online fanbase, with active fan sites, message boards and even campaigns that helped save the show from cancellation—twice.

The series, which also starred Majandra Delfino, Nick Wechsler, Colin Hanks and William Sadler, ran for just three seasons across two networks, but its fanbase is just as stronger two decades later, thanks in part to The CW's hit reboot that will return for its second season in 2020...with a familiar face behind the camera.

So crank up the iconic theme song by Dido, grab some Tabasco sauce and get ready for some out-of-this-world (sorry not sorry!) facts about Roswell in honor of its 20th anniversary, like the huge star who almost nabbed the role of Max...
