Yeah, there are definitely bits from RE and RE2 there but I also think that RE3 might have some part in this film, given that there is a character who looks a lot like the RE:3R Carlos in some shots. Obviously Chris, Claire, Leon and what looks like Albert Wesker too.
Is this a feature film or a TV miniseries? I can't see the entire story of the Raccoon City Outbreak fitting into a 120-minute theatrical release without it being abridged to mincemeat. Basically, any attempt to compress the first two or three games into one film would be an inevitable disaster.
