While The X-Files had an incredibly successful crossover in “The Springfield Files,” the classic episode only worked because of a confluence of vital factors. Crossover episodes are notoriously difficult to get right. Even the strongest shows tend to fumble their attempts to balance their appeal with that of another series, often resulting in outings that disappoint viewers of both shows alike. That said, if any show were likely to pull off this tricky feat, it would probably be one of the most acclaimed comedies in the history of the medium, namely The Simpsons during its legendary Golden Age (seasons 3-12).
The Simpsons proved that it was possible to pull off an ingenious crossover with “The Springfield Files” (season 8, episode 10). An unexpected meeting between The X-Files and The Simpsons, “The Springfield Files” saw Homer attempt to convince the denizens of the skeptical titular town that he had encountered an alien in the forest. “The Springfield Files” (which originally revealed that Chief Wiggum was an alien) was a rare crossover that impressed fans of both shows, prompting viewers to wonder how the show pulled this off.
Not only did “The Springfield Files” work as a classic, critically acclaimed Simpsons episode in its own right, but the outing also managed to function as a sharp, fast-paced, and affectionate parody of The X-Files. So, how did “The Springfield Files” avoid the pitfalls that so many crossover episodes fall afoul of? Three primary factors helped “The Springfield Files” find success. Picking the tone of The Simpsons and sticking to it (instead of attempting to also feel like The X-Files), mocking The X-Files relentlessly but warmly, and using the existing formula of The X-Files episode to shape The Simpsons episode all allowed “The Springfield Files” to not only avoid being seen as a cheap cross-promotion (like The Simpsons more recent Avatar 2 “joke”) but even become one of the only crossover episodes that is considered to be a standout success on its own .
The Springfield Files Feels Like The Simpsons
Unlike many crossovers, "The Springfield Files" could pick the tone of one show and stick with it. While Treehouse of Horror Halloween specials, “The Springfield Files” is clearly more concerned with jokes than scares and the episode isn’t worried about failing to faithfully recapture the creepy atmosphere of The X-Files. This means that the writing is as strong as any Golden Age Simpsons outing, with dozens of jokes per minute and a ludicrous, goofy tone that isn’t altered by Mulder and Scully’s arrival.
The Simpsons Made Fun Of The X-Files
While not every crossover struggles with merging two competing tones, many of them hit another pitfall. As seen when The Simpsons and The Critic had an earlier crossover episode, The Simpsons hasn't always been comfortable being used as a promotional vehicle for other shows and struggled to introduce new characters in a way that doesn’t feel forced. While that episode was largely strong, the scenes with The Critic’s hero felt off in a way that was hard to pin down. While contemporary episodes of The Simpsons prioritize celebrity cameos to an uncomfortable extent, “The Springfield Files” avoided this and instead mocked not only The X-Files but even Fox, the network that aired both shows.
In contrast with its uncomfortable promotion of The Critic, The Simpsons positively delighted in making fun of The X-Files (which was less in need of free advertising). From Mulder’s swimsuit FBI ID picture to his insistence that the FBI is “hardly concerned” with matters like an international crime syndicate, "The Springfield Files" mercilessly mocked The X-Files and was a funnier outing for it. Not only that but the cheeky fourth-wall-breaking moment where Bart and Homer turn to the camera and mug after promoting Fox’s TV shows is clearly intended as a dig at the network that is home to both shows.
The X-Files Formula Fits The Simpsons
While a big mistake often made by The Simpsons is the show’s tendency to feature first-act subplots that function as funny standalone cartoon shorts but don’t connect organically to the main story of the episode, this formula aligned perfectly with The X-Files crossover. Probably the most fortunate coincidence that made "The Springfield Files" work was the unique formula of an average episode of The X-Files. The fact that most “monster of the week” X-Files episodes began with a cold open that didn’t feature the main characters (because the show was busy setting up the episode’s mystery) meant that “The Springfield Files” could afford to do the same. This allowed "The Springfield Files" to feature an extended opening segment (the first act of the episode) that focused on classic Homer antics, making the introduction of Mulder and Scully feel less intrusive. By the time Mulder and Scully arrived on the scene, some of the strongest gags in “The Springfield Files” had already taken place.
Like a well-written Simpsons Treehouse of Horror segment, the opening scenes of “The Springfield Files” justify Mulder and Scully’s inclusion in the episode without feeling forced while also parodying The X-Files before the show's characters are even explicitly mentioned. By the time the characters arrive in Springfield, viewers familiar with The X-Files would have already been reminded of the series by Homer’s misadventure which, while hilarious, accurately recreated the standalone cold open formula of The X-Files while also adding in a string of goofy, over-the-top sight gags. Thus, where The Simpsons couldn’t pull off Family Guy and The Critic crossovers with as much aplomb, the sheer difference between the tone of The X-Files and that of The Simpsons, along with the fact that both shows featured cold opens, worked in their favor. Thus, The Simpsons made this The X-Files crossover a classic and avoided the pitfalls that plague so many comparable episodes.
