The cast and crew of Supernatural wrapped production on their final episode yesterday. Jensen Ackles, Jared Padalecki, Misha Collins, and more said farewell to the long-running, fan-favorite TV series on social media, thanking fans for all of their support over the years. The CW's Supernatural premiered back in September 2005 on The WB. The pilot was viewed by an estimated 5.69 million viewers, and the ratings of the first four episodes prompted the network to pick up the series for a full season.

It's been a long run for the cast and crew of Supernatural who have all become a tight-knit family behind-the-scenes. After 15 years of working alongside a lot of the same people, one can imagine that the final filming was an emotional event for all parties involved. Jensen Ackles had tough time hearing the alarm clock in the morning yesterday. Ackles had this to say about the final day on the set of Supernatural.

"Woke up at 6am this morning. That alarm went off with a heavy tone. Today is the final day of a 15 year journey. One that has changed my life forever. To those I have worked with on this journey and to those who have watched and supported... you will never understand my great appreciation for you. 'Thank you' doesn't cover it. There just aren't words. I'm so grateful for these memories that I will carry with me forever. What a ride it has been. And what a run."

Jared Padalecki also posted on social media before heading into the final day of Supernatural. Like Ackles, he is very grateful for the support that fans have given the show over the past 15 years. Even through the public health crisis, the cast and crew of the show kept the fans up to date with the final episodes, keeping a dialogue going and promising a surprise at the end of the uncertainty. The aforementioned surprise is the one-hour retrospective airing before the final episode in November. You can read what Padalecki had to say below.

"Well, here goes... I write this as I head to my last day of #Supernatural. My last day with #SamWinchester. Obviously, my head is spinning and my emotions are stratospheric, but there's still a bit of time left on the clock. Thank y'all SO MUCH for the incredible amount of love and support that's been headed our way, in these final hours. It's definitely been felt."

Misha Collins simply said, "Thank You Supernatural. You've changed my life in so many ways and you changed the world for the better." Series creator Eric Kripke posted an image of their first day of filming back in 2005 and said, "I'm grateful & love you all beyond words. But it's only over when you say it is, #SPNFamily. In the words of Kim Manners (RIP): Kick It In The Ass."

Jensen Ackles believes that Supernatural will return at some point down the line. The actor expects the cast and crew to reunite for some specials in the years to come, which should be some good news for fans to hear as they wait for the rest of season 15 to be delivered.
