I'm really looking forward to watching this movie once I get the chance.

Here's some interesting bits of trivia for you: Zangief isn't actually a bad guy in the Street Fighter series. One of the producers in the movie really didn't like Zangief as a CPU opponent back in the day, finding him cheap and irritating, so as a result he viewed him as a bad guy, and to reflect that made him one in the movie. Similarly, Smoke and Cyrax from Mortal Kombat aren't bad guys either (well, Smoke is only a bad guy in MK3 and MKeception, where he's unwillingly mind-controlled in both games, and Cyrax is in a similar boat in MK3 and MK9), yet they both show up in the Bad Guys Anonymous club.

The various companies whose bad guys were used in the Bad Guys Anonymous club kept wanting changes to be done in regards to how they depicted their characters. They wanted their villain characters to be increased in size to reflect their actual size in their games. Eventually, it came to the point where Ralph was a midget in a room full of giants.

Mario was meant to cameo in Wreck It Ralph, but they couldn't really find a way to have him cameo so that his cameo would be major enough to pay respect to him, yet wouldn't majorly impact the story. They are wanting to ensure he has a cameo for a potential sequel.
