GothicNarcissus wrote: A good compromise would be to just build up a bit on the references that were made in the episodes without going into much detail. Something vague like: “Elsa and Anna lived in seclusion for years due to Elsa's uncontrollable powers, then their parents died in a ship wreck. Elsa's powers manifested during her coronation and went wild, so she run away and hid herself in an ice palace until Anna helped her control them through her love. In doing so they meet Kristoff and defeat Hans, and bla bla.” You know, just written decently. :P We have the events in Frozen chronicled in the past of the characters based mostly on what they said on screen in Once, but without getting overly long entries or spoiling the movie to the four or five people on Earth who haven't seen it yet.

I think GothicNarcissus is right. A&E have confirmed that the movie is canon. I think as you are watching the episodes, a basic overview of the movie may be needed. Just the basic necessities though, such as things mentioned on OUAT. The charactor pages would look really weird if it just jumps straight onto where OUAT begins, because part of the charactors' arcs start in the movie. It only needs to be a quick summary of the movie.
