Promoted Fanboy: Several former and current professional players are now or have worked behind the scenes with Capcom on their games. Specifically David Sirlin, who worked on Super Street Fighter II HD Remix and Seth Killian, who was formerly the "Special Adviser for Street Fighter" among other things. HD Remix also had a soundtrack done by artists from OverClocked ReMix meaning that the entire game's soundtrack was done by promoted fanboys.
Urban Legend of Zelda: Some fans believe Mike is really Balrog, or M. Bison as he is called in Japan, since the "M." in M. Bison originally stood for Mike.
Rumor also has it that Joe was going to appear in Street Fighter Alpha 3 but was replaced by Cody at the last minute. There's also the rumor that The Ghost, a kickboxer in Final Fight: Streetwise, is supposed to be him.
Early drafts of the script focused on Ryu and Ken as the main characters. However, when Jean-Claude Van Damme signed on to appear in the film he insisted on being Guile and making him the central character. So the script was rewritten.
The production team had originally made Guile and most of the "good" characters UN peacekeepers. But due to visits from representatives of the UN, they changed it to AN or Allied Nations.
In the year 2003, the movie was slated to finally have a sequel. Van Damme and Damien Chapa were to return as Guile and Ken, Holly Valance was to take over for Kylie Minogue as Cammy, Byron Mann was in talks to return as Ryu and Dolph Lundgren was supposed to appear in an untold role. However, once the rights to the franchise left Universal and went to Fox, the sequel was scrapped and turned into a reboot called Street Fighter: The Legend of Chun-Li, which was far, far less received than this cult classic.
In the sequel it would have been revealed that Blanka and Dhalsim survived and the chemicals that made Dhalsim bald also gave him his stretching powers.
They originally wanted Fabio to play Vega, which is understandable considering Vega's narcissism, and would've made a hilarious "Funny Aneurysm" Moment years later when Fabio's face was smashed after colliding with a goose on a roller coaster — no, you did not misread any of that.
Talking to Himself: Ken, Blanka and Rolento are all voiced by Scott McNeil, while Balrog, E. Honda, Dee Jay, T. Hawk and Fei Long are all voiced by Paul Dobson.
Also, it is very common to notice when a random Mook or innocent bystander is voiced by one of the main characters' voice actors.
Humorously enough, this actually gets Subverted in one episode, where Burke (voiced by Gary Chalk) is spoken to by a random person that was also voiced by Gary Chalk, but Rory (voiced by Scott McNeil) is the one that replies to the man, even interrupting Burke before he even uttered a single word to the other person.
