The end of an era! After 15 years on the air, Supernatural came to an end in November 2020.

Starring Jared Padalecki and Jensen Ackles, the CW show premiered in 2005 and immediately became a fan favorite. The series followed brothers Sam and Dean Winchester who grew up hunting monsters (think vampires, werewolves and demons). When their dad went missing, the boys found themselves looking for him while keeping the world safe from everything that goes bump in the night. Now, the brothers Winchester are all grown up and saying goodbye to the characters they played for a major portion of their lives.

“The feeling I had that day was more like pride, emotional pride,” Jensen told Entertainment Weekly in November 2020 about his final day on set. “Like, look at what we’ve done. Look how far we’ve come, and look at these people who helped us build this incredible piece of art that we’ll get to hang our hats on for the rest of our lives.”

Months prior, during an April 2020 interview with EW, the actor recalled the hard work he put into the show over all these years.

“The 23-episode seasons were nine and a half months of filming,” Jensen explained. “It was a lot of work, but I always came back to: I still enjoy it, I still like telling the story, I still like these characters and the people I work with.”

All these years later, and fans are still as obsessed with the show as they once were. Aside from Jared and Jensen, there were tons of major stars who made appearances on the show before they were famous. Take a walk down memory lane and uncover all the celebs fans forgot were on Supernatural. As it turns out, a lot of famous faces actually appeared on the spooky series. Ashley Benson, Cory Monteith, Finn Wolfhard, Calum Worthy and more were in guest starring or recurring roles. Now, fans know these stars from all of their other accomplishments, but everyone gets their start somewhere!
