I'm thinking somewhere between Monsters Inc adjusted ($364 million) and Toy Story 2 adjusted ($390 million) sounds about right for Frozen. As a matter of fact, if it lands around $380 million, I'm assuming taking out 3D would put it around $350 million or so in terms of sheer tickets. That would have it in the same attendance area as Toy Story 3 which I'd have to say is a pretty huge accomplishment.
