26 oddly similar pairs of movies that came out around the same time

Marvel/Warner Bros.

"Batman v Superman: Dawn of Justice" pit the legendary Dark Knight against the Man of Steel in March, and now we have another big superhero showdown in "Captain America: Civil War."

While the two films should be markedly different — Warner Bros.' film will use "BvS" to introduce members of its Avengers-like team to audiences — both show the government calling for superhero regulation against the Avengers and Superman, respectively.

Both films also have a villain pulling the strings to force the heroes against one another.

The marketing campaigns also make the two films appear striking to those who aren't huge comic fans.

Both pit two superheroes against each other and ask fans who will emerge victorious in a giant brawl. One redditor humorously pointed out that you could call "Civil War" "Captain America v Iron Man: Dawn of Spider-Man."

This isn't the first time two similar-sounding films were set for release around the same time, and it certainly won't be the last.

Often called "twin" films, Forbes contributor Mark Hughes said in a 2011 Quora post that while sometimes the release of two similar films is just coincidence, it could be to piggyback off a competitor's potentially successful — or already successful — project.

Read the rest of his explanation here, and keep scrolling to see 25 more "twin" films that have come out months apart in theaters over the years:

1993/1994: "Tombstone" and "Wyatt Earp" are centered around Western lawman Wyatt Earp.

Box Office
"Wyatt Earp": $25 million
"Tombstone": $56.5 million

Neither film did overwhelmingly great at the box office. "Tombstone," starring Kurt Russell and Val Kilmer, edged out the Kevin Costner and Dennis Quaid film from Warner Bros.

1997: "Dante's Peak" and "Volcano" revolve around the cast outrunning erupting volcanoes.

Box Office
Dante's Peak": $178 million 
"Volcano": $122.8 million

Fox got a little excited with its over-the-top posters for "Volcano." The film did nowhere near as well as Pierce Brosnan's volcano epic in the states; however, the Los Angeles centered movie picked up overseas.

1998: Earth was nearly destroyed in "Armageddon" and "Deep Impact."

Box Office
Armageddon": $553.7 million
"Deep Impact": $349.5 million

Bruce Willis saves the world from an asteroid in the first film, while Robert Duvall tries to stop a massive comet from colliding with the planet.
