According to The Tommy Westphall Universe Hypothesis, nearly all of American television takes place in the mind of an autistic child. The theory first appeared in 2002, when writer Dwayne McDuffie wrote Six Degrees of St. Elsewhere for the Slush Factory. For those of you don’t know, St. Elsewhere was a slick, well written and acted drama series about the ...

Since your question asks What is the first crossover movie? I'll submit two of the earliest I have found, depending on your definition of "crossover". For movie horror/sci-fi franchises, there is Frankenstein Meets the Wolf Man (1943). But I think the earliest could be Laurel and Hardy's appearance in the Our Gang comedy short Wild Poses (1933). Both Our ...

Film corporation collaborations are not as uncommon as one might believe. This is especially true when dealing with music or music artists signed to one label that is under the umbrella of another corporation. Granted in those cases the film corporation really tries to pull music and artists from under it's own parent company labels but such is not ALWAYS ...

Detective John Munch, played by the same actor, Richard Belzer, has appeared in at least a single episode of the following distinct television series, though in some cases, multiple episodes: "Law & Order: Special Victims Unit" "30 Rock" "The Wire" "Arrested Development" "Law & Order: Trial by Jury" "The Beat" "Law & Order" "Homicide: Life on ...

I would think Alien vs. Predator would be an example of combining franchises, which was released in 2004. While not a critical success (garnered only 22% Tomatometer), it did gross $80.2 million. It even spawned a sequel, Aliens vs. Predator: Requiem in 2007.

You've got a lot of properties listed here, so for the sake of clarification, let's break them out. The Marvel Cinematic Universe (MCU) is where the films produced by Marvel Entertainment / Disney take place.

Arrow and The Flash are part of same canon called Arrowverse and have crossover almost every year and even more then once sometime: The Flash S01E01: It's Pilot for the Flash show and Arrow came for a speech/dialogue only and don't have much impact of it on Arrow show itself, You might already know S02E8 and S02E09 of Arrow is kind of backdoor pilot of ...

It’s going to happen with the cooperation of both the studios, it was in talk from long. Discussion was from reboot to sequel. Spider-Man is a big part of Civil War story line, which is happening in Captain America: Civil War. From Wikipedia Marvel Cinematic Universe page: In February 2015, Sony Pictures and Marvel Studios announced that Spider-Man will ...

If we're not talking public domain characters, then my mind immediately turns to Japanese monster movies. There are several monsters with their own movies, but on occasion they would appear together in a "Vs." movie. Earliest one I could find is King Kong vs. Godzilla, which was release in 1962.

Are you asking specifically about comic book franchises? There have been no shortage of public domain crossovers, or crossovers between a branded character set and public domain characters. (For example, The Three Stooges Meet Frankenstein (1948), The Three Stooges Meet Hercules (1962), The Seven-Per-Cent Solution (1976, and has Sherlock Holmes meet Sigmund ...

I've found no references about this anywhere online, so I'm going to say no, they are not (deliberate) references. There are plenty of Easter Eggs that Disney, and Pixar in particular, are famous for. For an example of these, see this link. However, no member of the production team for any of these films has made any comment about observations like yours, ...

"Forever Red" from Power Rangers: Wild Force includes characters from 9 shows with speaking roles To commemorate the 10th anniversary of the Power Rangers franchise, the episode "Forever Red" of Power Rangers: Wild Force featured Red Rangers from every Power Rangers TV show to date teaming up to fight an enemy. Every one of them has speaking roles. Jason ...

Supergirl happens in one of the various unnumbered parallel universes to The Flash and the Arrow-verse. It is neither Earth-1, where Arrow, The Flash, Vixen, or Legends of Tomorrow occur, nor Earth-2, home to Jay/Zoom, the 2nd Harrison Wells, and Jessie Quick, where technology seems to have taken off decades earlier (Very Zee-Rust). Update: A season later, ...

I hate to send you to a website, but there is a master list of crossover appearances maintained at Poobala. The site is physically elderly, to the extent that it uses frames, and it last had a major update in January 2012, but it is quite comprehensive. There are so many crossovers listed that it would be futility to copy them all over here. The ...

Wikipedia has some information about this. For instance, Detective John Munch from Homicide: Life on the Street (NBC) appeared in an episode of The X Files (FOX). It's rare, but it happens.

Digging a little on IMDB, I came across The Justice League Part One. I am guessing the spectacular response to Avengers should hurry them along... In January 2008, Warner Bros. announced the film was on indefinite hold, allowing options to lapse for the cast. The studio felt the script needed perfecting, which was impossible because of the 2007-...

As far as I know, nobody confirmed coming from Earth-199999 have crossed over to other Marvel universes. However, the opposite have happened; according to the Marvel Wikia, the Young Avengers visited the MCU while looking for the character Speed, in Young Avengers Volume 2 #8. In the same issue there's also an Easter egg, showing Earth-616's Loki's passport ...

I watch both shows and have seen both parts of the crossover, you probably can watch it without seeing the previously shown Sleepy Hollow episodes as long as you at least know the rough premise of SH as it was (from what I can tell) intended to act as a way of attracting Bones fans to Sleepy Hollow so while it forms part of the arc for season three it's ...

The showrunners of Bones have always been extremely coy about whether those supernatural elements are real, or have a "real world" explanation. You are correct in your assumption that shows like "Hero in the Hold" are intentionally left vague (as are later episodes where, for example, we apparently see a legitimate psychic/medium.) However, there have been ...

If we disqualify the Tommy Westphall Universe… An issue with the Tommy Westphall universe is that many shows are only linked by Easter eggs (e.g. the TARDIS is in the background of a single shot, things like Morley cigarettes or the Yoyodyne company exist), which isn't really in the spirit of the question. Also, plenty of shows in that universe are not at ...

Not sure if OP meant that Bones interlinked characters/episodes with the tv show Crossing Jordan, I wasn't aware of crossovers with CSI but maybe I missed them. Not sure if this counts but Joss Whedon's two shows Buffy and Angel were written in the same universe however at a later time Angel was moved to another television network. This is why there stopped ...

Recently the Andrew Garfield Spider-Man, Tobey Maguire Spider-Man and Ultimate Spider-Man TV show Spider-Man were involved in the spider verse event where alternate spider-heroes teamed up to defeat the inheritors: energy vampires who hunt alternate spider-heroes.

Buffy and Angel? Quite a few episodes there.

There were the Beverly Hillbillies/Green Acres/Petticoat Junction crossovers in the 1960s.

I am up to date with only Flash and Arrow You should be fine. To date only Flash and Arrow have had the Crisis as a plot point, the other shows have not featured any elements of the proposed crossover although characters from other shows are expected to feature in the crossover episodes. At best, the pre-crossover episodes of other CW /DC shows have only ...
