Adaptation

I decided to choose Interview with a Vampire for my movie screenplay, and viewing it as a costume designer. I think the first place I would look would be the time period the film is set in. You wouldn't want to have a vampire movie set in the 1800s with characters that are wearing clothing from present day. That has always been a pet peeve of mine when movies are set in one time period but dressed inappropriately. It just makes the film bad to me. Either way, i would first look to the time period and then to the description of the outfits if there was one. If not, I would do as much research as possible on that time period for clothing. Maybe adding a bit of personal touches but nothing that would make it seem unrealistic. Each scene would have specific costumes which would require it's own research. Honestly, I would base it on personal preference and historical facts.
