The uncredited actor who played the doctor, who's team is kept in the cafeteria, is Bernard Behrens.
Dr. Murnau, the scientist who seals up himself and his team in BioTek's cafeteria, was never credited in the film, so nobody knows which actor played the role. It is possible that his actor didn't want to be recognized for working in the film, or that the cast information on him was left out by mistake and then lost.
The bio-hazard project codename, "Blue Harvest", was also the original production codename for Star Wars: Episode VI - Return of the Jedi (1983) in 1983. Both films were released by Twentieth Century Fox.
The working title for the film was "Biohazard".
The name of the agricultural factory is 'BioTek Agronomics". Many people assume it's misspelled when in fact it was misspelled on purpose. Using "BioTek" rather than "Biotech" avoided issues with real corporations that used the proper spelling, and "agronomics" is a play at the words "agricultural" and "economics" put together.
