Instead of just taking duration to be the measure of any curve between a pair of points in spacetime, cinema takes it to be the time that has passed between a film’s beginning and end and uses this to classify films according to their length. According to the British Film Institute, a feature film should be 40 minutes in length or more. The Screen Actors Guild puts its shortest acceptable feature at 80 minutes.
If a film is, by cinematic convention, defined as having a beginning and an end, what would a film be in special relativity? Beginning and end form a pair of points, but the film has no definite length, or more precisely, no definite answer can be given to the question of the time difference between beginning and end. The same film has as many possible durations as there are curves that connect the points that were arbitrarily named beginning and end
