Here is a movie teaser the production team put together for the film.
This movie teaser was possible because the production team decided early on to film the movie chronologically (may be the wrong term, as the scenes appear in the screenplay). Since the hostage is predominantly a single location film, it was much easier to achieve.
Benefits to the production.
Filming in this manner meant that they could edit it together as it was being filmed. This meant that things that didn’t flow from scene to scene could be addressed quicker.
An extra benefit was that small “joining shots” could be grabbed the next day if needed to make the visuals flow better.
Anyway after all that talking here is the teaser for The Hostage.
