·         Early on in the series, Dean's cell number is given, and for a while the studio had it set up so that anyone dialing the number would hear Jensen Ackles reading the message: "This is Dean Winchester. If this is an emergency, leave a message. If you are calling about 11-2-83, page me with your coordinates." The number is 1-866-907-3235.

·         The car Sam and Dean drive is a 1967 Chevrolet Impala, which has been nicknamed the Metallicar by fans of the show. The show uses five black Impalas.

·         The only known sources of income for the Winchesters are credit card scams, poker games and playing pool.

·         Dean's car, up until episode 2.20, had Kansas (the brother's origin state) plates with the number KAZ 2Y5. It currently now has Ohio (Supernatural's creator Eric Kripke's home state) plates with the number CNK 80Q3.

·         Producers considered several methods of motivating Sam to take to the road with Dean. Turning Jessica evil was an option briefly, but in taking a page from Star Wars it was decided that her death would be the ultimate motivation for leaving home.

·         After the first season, the show was picked up by The CW because The WB merged with UPN to form The CW.

·         While filming season two, Jared Padalecki (Sam Winchester), broke his wrist after performing one of the stunts on the show.

·         Many of the episodes are based on existing legends, myths, and ghost stories. ([Spoiler] For example the episode "Crossroads" is based in part on the legend of Robert Johnson - who in turn borrowed it from another Blues singer.)

·         Most season two episodes are either named after movies ("Children Shouldn't Play with Dead Things", "The Usual Suspects") or classic rock songs ("In My Time of Dying", "Born Under a Bad Sign", "What is and What Should Never Be").

·         The round blue/skull sticker on the top of Sam's season one laptop is from a prominent local North Vancouver mountain bike company, Deep Cove Bike Shop.

·         The character of "Bobby Singer" was named after executive producer Robert Singer.

·         The original concept had a reporter going to investigate the urban legends and writing about them in his column instead of having the Dean and Sam concept.

·         Sam's birthday is May 2nd (born in 1983).

·         Dean's birthday is January 24th (born in 1979).

·         Originally Jensen Ackles auditioned for the role of Sam Winchester. When Jared Padalecki came in and read for Sam a slight recasting was done. Producers called Jensen and asked if he'd rather use his charm for Dean, saying he was the Han Solo character of the duo and what kid didn't grow up wanting to be Han Solo? Jensen accepted. It became known that he was previously interested in that role, because Dean was funny.

·         Riverview Hospital, a large mental health facility used as the main set in the season 1 episode Asylum, has also substituted for a prison, a regular hospital, and an apartment building on different episodes of the show. This is evidenced by seeing the same distinctive staircase in different episodes.

·         The Latin inscription on the barrel of the Colt says 'non timebo mala', which translates to 'I will fear no evil'.

·         Jeffrey Dean Morgan (John Winchester) is only 12 years older than his on-screen oldest son, Jensen Ackles (Dean Winchester).
