* DawsonCasting: 22 year old Allison Pill plays 17 year old Jane. Also a slight example, 17 year old Creator/BrittRobertson plays 14 year old Cara.
* MethodActing: The actors all spent a month together in the house where the film is set to create a more familial atmosphere.
* SeparatedAtBirthCasting: An interesting case -- Creator/AlisonPill, Creator/BrittRobertson, and Creator/MarleneLawston pass quite convincingly as sisters, though none of them look a thing like Creator/SteveCarell.
