The 2001 BBC/HBO television film “Conspiracy”, which dramatizes the 1942 Wannsee Conference, used an almost theatrical performance style during shooting. What this meant was the performers stayed in costume and character from the start to the end of each day of filming. Also, a set was used with solid (non-moving) walls and ceilings, to reinforce the reality of the setting, and eliminate any delays for changing camera or lighting setups. It didn’t stop there though.
In addition, the action was filmed in extremely long sequences, sometimes 20 pages or more of script at a stretch, which is unusual in this type of production, but many of the actors in the film had a Shakespearean background so having to memorize this amount of dialogue was not a new experience for them.
This production style required the use of the Super 16 film format because of the longer film magazines available for those cameras, and also the smaller size, allowing the cameras to get in very close to the performers sitting around a conference table, the setting used for the bulk of the story.
The theater was the first form of grand storytelling. Makes sense it would find itself rooted in modern forms as well.
