So, a few thoughts on Mortal Kombat. First off, I'm considering Ming-Na Wen for the role of Kitana.
Next, what honestly surprised me in my research on the first movie is how much of it influenced the later games.
- It introduced the idea of a realm needing to win 10 tournaments in a row to invade another realm.
- It made Raiden into a mentor figure and gave him white hair.
- It introduced Liu Kang/Kitana and Johnny/Sonya (though the former was likely based on the original actors for the games, Ho-Sung Pak and Katalin Zamiar, dating during the making of MK2)
- Trevor Goddard's Kano and Cary-Hiroyuki Tagawa's Shang Tsung being so well received that they pretty much became canon, including retconning Kano to be Australian and giving Shang Tsung his catchphrase.
- Scorpion's teleportation ability. The same would happen with Kitana looking more like Talisa Soto.
- Sonya's finishing move on Kano.
- The $500 sunglasses and subsequent Johnny/Goro feud were alluded to in later games. Plus, Johnny's motivation for joining the tournament came from the game
Like, I'm really not sure what would need to change about the plot of the first movie (apart from replacing the CG reptile with just having Shang Tsung ordering an actual human Reptile to spy on Kitana, who then goes invisible) which is why I was mostly looking for tweaks. Like, I know when we get to Annihilation, we'll get us some overhaul, but this movie seems surprisingly tight.
