The first thing I should point out, is that movies are almost Never shot in chronological order, or in other words, in sequence of the events as they would unfold or "script order." This is pretty common knowledge, but don't beat yourself up if you didn't know already. For Dolly Parton's first motion picture (Nine to Five), she memorized the entire script, including the other characters' lines. Apparently, after letting on that she thought movies were filmed in chronological order, co-star Lily Tomlin burst out laughing.
Movies are shot out of sequence for a number of reasons. Among these reasons are; renting out locations or studio space, lighting, weather conditions, and most importantly, the availability of an actor. All of these basically boil down to time and money.
So with budget and time constraints almost always working against shooting a film in chronological order, what would drive a filmmaker to pursue such a course?
