Marathons appear on POS as a single screening. By default, only the first film in the group is listed (for example: The Hobbit 1), but the screening time recorded includes the entire group (for example: 07.05pm-02.39am). It is possible to use the Marathon Film field in Showtime Manager or Program Scheduler to select a particular Film record for the Marathon as a whole to be marketed as.
It is important to understand that the Attributes and Movie Format displayed on POS and signage come from the first session in the Marathon only.
For example: If The Hobbit 1 is 2D, but The Hobbit 2 and The Hobbit 3 are 3D, POS will advertise the entire Marathon as 2D.
