1. Kripke’s original concept was a series which centered around a pair of reporters who travel across the country investigating urban legends for a newspaper column. In fact, the series wouldn’t have even been named Supernatural – early drafts were written under the title Unnatural.

2. In the original draft of the Supernatural pilot, Kripke’s plan was for the brothers to find their dad dead on the ceiling – not their mom!

3. The truth is that Ackles initially auditioned for the role of Sam Winchester, not Dean! As it turns out, it wasn’t until Padalecki auditioned for the role of Sam that the producers asked Ackles to come in to read for Dean.

4. Castiel was only supposed to appear in a guest starring role on the series but due to the fans’ outpour of upendo for the character and his portrayer, Misha Collins, the writers decided to make him a series regular.

5. In the series’ early days, mashabiki that called the number aliyopewa kwa Dean (1-866-907-3235) would receive the following message read kwa Dean himself, Jensen Ackles:

“This is Dean Winchester. If this is an emergency, leave a message. If wewe are calling about 11-2-83, page me with your coordinates.”
November 2, 1983 is of course the tarehe in which the Winchester brothers’ mom died. As time went kwa the message was changed to fit in with the series’ current storylines with callers instead hearing Dean relay the following message:

“Dad? We really need to hear from you. Leave me a message, text me, check your jwinchester1246 email. Anything. We have new info.”

6. With its eleventh season, Supernatural will become the longest-running, consecutive Sci-Fi series to-date – a record currently held kwa The WB/CW’s superhero drama Smallville (217 episodes).

7. Same location has been used as the back-drop to multiple settings in multiple episodes.The best example of location recycling is the series’ use of the Riverview Hospital, which was used as the main set in Season 1’s Asylum. Throughout the series’ early season the mental health facility was also used in various other episodes as an apartment building, a prison and a regular hospital.

8. Winchester brothers often go undercover with aliases that are a direct homage to various rock stars/duos. Among the numerous orodha of tributes scattered throughout the series’ seasons: Angus and Young (AC/DC’s Angus Young), Plant and Page (Led Zeppelin’s Robert Plant and Jimmy Page), and Tyler and Perry (Aerosmith’s Steven Tyler and Joe Perry).

9. In the early stages of production, Dean’s beloved vehicle was originally supposed to be a 65′ Mustang. In the end, the Impala won out as it was alisema to look rougher than the 65′ mustang and it could also fit a body in its shina – something that’s come in very handy over the years.

10. Jeff Budnick revealed that the series uses eight Impalas in total, each with their own use.

“We have 8 in total, 5 that run and all have been used at one time We have cars that are built for different applications such as a “burn out” car, “slide car”, dark tint glass etc. They are a very dependable car considering the demands the film industry requires.”

11. Winchester brothers take on a siren they all share a common similarity: they are always named after a Disney heroine.

For example, way back in the Season Four episode Sex and Violence, Sam and Dean investigate a string of deaths which end up being linked back to a siren named Belle (which happens to be the princess at the center of Disney’s Beauty and the Beast). Across the various seasons, Sam and Dean have also encountered sirens with the name Ariel (The Little Mermaid), Aurora (Sleeping Beauty), and jimmy, hunitumia (Aladdin).
