In an interview, Noboru Sugimura stated that Leon was originally supposed to start out in civilian attire. There would've been a scene between him and Marvin at the police station where he'd change into his police uniform.

"It’s true that with Racoon City destroyed, the police wouldn’t be actively on duty, so there’d be no real need for Leon to change into his uniform… but we wanted to show his determination to protect both the city and his principles by having him change into his uniform regardless. It was a scene with a lot of meaning. Unfortunately, due to a problem with the CG it got cut."
