Bruce Willis, Bill Murray, Frances McDormand, Edward Norton and Tilda Swinton amongst those rumored to be in. The synopsis from Deadline Hollywood which, along with the presence of McDormand, makes this one feel a bit more Coen Brotheresque than your typical Anderson film:

Moon Rise Kingdom is set in the 60s. Two young adults fall in love and run away. Leaders in their New England town are sticking the idea that they’ve disappeared and go in search of them. Norton will play a scout leader who brings his charges on a search. Willis is in talks to play the town sheriff who’s also looking, and who is having an affair with the missing girl’s mother, the role McDormand is in talks to play. Murray, a regular in Anderson films, will play the girl’s father, who has his own issues.
