Revealing mistake: At the black market, Honda and Balrog bring Ryu into the tent that Ken is already restrained in. When they enter, Ryu begins to fight with Honda and Balrog but Chun-Li ends their fighting by emerging from a curtain wielding a knife. Ryu backs into the knife and it bends.

Character mistake: When Guile promises to rescue the hostages while on camera with Bison, he makes it a point to mention Charlie by name to reassure him that he wasn't forgotten. Anyone in charge of a major hostage recovery operation would avoid naming a specific hostage unknown to the enemy due to the special focus that the enemy may put on that hostage for further abuse. This was promptly proven when Bison specifically chose Charlie to transform into a beast due to Guile identifying him as a personal friend.

Trivia: Here's a brief list of the moves from the game that made it into the film: Ryu threw a fireball at Vega. Ryu does a hurricane kick against Vega. Vega did his rolling attack against Ryu. Ken does the standing uppercut against Sagat. E. Honda does the hand slaps against Zangief. Balrog does the wind-up punch against a Bison Trooper. Guile did two Flash Kicks against Bison. Cammy did a thrust kick against a Bison Trooper. Chun Li does the spinning bird kick against Bison.
Answer: When Guile storms Shadaloo headquarters with the stealth boat, he is accompanied by Cammy and a hugely modified (in terms of character) T-Hawk. At one point Guile asks about T-Hawk's headband. Being an aid to Guile, T-Hawk is in other scenes, but these are the most obvious.
