With the premiere of spinoff series Supernatural. Part of the show's charm is the affectionate and uninhibited friendship between its stars that has led to 15 years worth of iconic blooper reels.
The hilarious mistakes the actors made are not just limited to the 5-10 minute long gag reels. Some goofs actually made the final cut, alongside some inspired improv that catches the rest of the cast off guard. In fact, some of the funniest moments from the show come from what could be described as the actors' artistic liberty–In other words, they put a bit of themselves into their characters by messing around on set.
Dean Returns For The Lizard
In the episode "Wayward Sisters," Sam and Dean find themselves trapped in a hostile alternate universe. The food sources are just as plentiful as anyone might expect from somewhere nicknamed "the Bad Place." Dean roasts himself an otherworldly lizard over an open fire, imploring Sam to eat up since the two have no idea how long they will be stuck.
Dean seems to enjoy the taste of the lizard a little too much. The end of the scene shows him running back to grab the lizard on the stick, a moment that was not in the original script. According Nerds & Beyond's live tweet during a Q&A at the Orlando Supernatural Convention, Jensen Ackles claimed he chose to run back for the unfamiliar region's snack, not expecting the comical bit to stay in the show like countless other slapstick improvisations. Alas, editors agreed with Ackles that Dean would not leave food behind, choosing to keep the scene.
Castiel Neglects Personal Space
In Castiel's first appearance in season four, Dean is clearly confused as to why the angel is getting so close to him. The celestial being is practically nose-to-nose with the hunter due to his lack of interpersonal skills, prompting Dean to pull a face of total discomfort.
Misha Collins did not get this close to Jensen Ackles while staging the scene out, and according to Misha Collins at Chicago 2009 Supernatural Convention, this was not direction that they discussed beforehand. So, behind the chagrin on Dean's face in this scene is actually Jensen Ackles wondering why on earth Collins is getting so close to him, which makes for a hilarious re-watch for fans. It worked wonderfully for the scene, which remains the best-ever Supernatural character introduction.
Dean Hops The Fence
Fans love the season 12 episode "American Nightmare" for a few reasons, with form fitting sweaters at the top of the list. The episode also has a fan-favorite clip of Dean choosing to climb over a closed gate, clearly struggling to make it over the top, while Sam opts to simply walk around it.
The sibling moment was not originally in the script. Jensen Ackles told fans at Burcon 2016 that he hopped the fence because he thought it would be funny. He was right, it is funny, and flawlessly in character for Dean. Sam's expected reaction to his brother's nonsensical clamber over the barrier after taking his own logical route comes right from the mind of Jared Padalecki, demonstrating that he knows his character all too well.
Castiel's German Accent
In the second episode of season 13, "Exodus," the Castiel from the Apocalypse World speaks in a strong German accent. There is no apparent reason for Alternate Castiel's Germanic pronunciation, but some fans assume that his vessel Jimmy must have ended up in Deutschland at some point.
As it turns out, Alt Castiel was not meant to have a German accent in the episode. Misha Collins improvised the voice last minute, changing his performance to tone down the Nazi vibes, according to the fans who Castiel is still so many fans' favorite character favorite character.
Jack's Cheery Funeral
The writers may have intended for Jack's funeral to be melancholy, but the season 14 episode reveals a much cheerier ceremony for the supposedly dead nephilim. As it turns out, it can be difficult for Jared, Jensen, and Misha to be too somber for an extended period of time in a room together.
The actors decided to run with their goofy instinct and give Jack a light-hearted sendoff. The three can be seen laughing together while paying tribute to their fallen friend. During a meet and greet, Jared itted to Twitter @NorthernSprw that this is more Misha, Jensen, and Jared than Cas. The scene made the final cut, and the result is the feel-good funeral that Jack would have wanted, had he actually been dead.
The "Eye Of The Tiger" Performance
The end of "Yellow Fever" reveals a magnificent performance to "Eye Of The Tiger" by Jensen Ackles that is too good to just make the gag reel. In the scene that makes the actual episode, Dean just bops to the song while lying in the back seat of the Impala, but clearly he and Jensen share a love for the Survivor song.
In the makeshift concert that fans get to see before the episode's credits, the choreography is a little over the top for Dean, but right on the nose for Jensen. Ackles and Padalecki spoke about the spontaneity of the moment in an interview with one of the best fantasty TV series of all time.
"Son Of A Bitch!"
In the third episode of the third season, "Bad Day At Black Rock," Bela Talbot runs off with Dean's winning lottery ticket. Dean does not realize that the tickets are gone until the end of the episode. He lets the loss sink in for a moment before exclaiming his catchphrase "son of a bitch" in a fit of frustration.
The expletive was not in the original script, as the scene was meant to end on Dean's silent realization. Jensen Ackles added it in himself while in the early stages of making the phrase a recognizable bit for fans. Viewers who watch the scene closely can even see Jared Padalecki stifle a laugh when he begins to see it coming, a goof that that Jared Padelecki itted to at the Los Angeles Supernatural Convention in 2008. The producers chose to keep it in the show because it is a reasonable response for Dean, and because Sam likely would have laughed at his brother the same way Jared laughs at Jensen.
Dean Drops The F-Bomb On The Scooby Gang
Some fans may believe that Supernatural went on far too long, but without the later seasons, viewers would have never gotten to enjoy bizarre episodes like "Scoobynatural." The episode places Sam, Dean, and Castiel in the world of Scooby-Doo, a universe where they would fit in perfectly if they were less TV-14.
Amidst a motivational speech to hype the Scooby Gang up after forcing the cartoon characters into an existential crisis about life, death, and reality, Dean drops a hilariously-timed F-bomb. This was not the original line, but Jensen Ackles threw it in as a joke, according to Misha Collins at 2008 Seattle Supernatural Convention. Producers decided that the moment was too wonderfully obscene to cut, opting to just bleep over it. If anything, the bleep enhances the raunchy effect that is poetically out of place with the Scooby-style animation.
