Warner Bros. and Legendary's “Dune: Part Two” grossed an estimated $4.5 million on Wednesday. Its total domestic gross now stands at $172 million. This is an indication of a possible $30 million third weekend coming up for ‘Dune 2’ — that’s only a 30% drop. It should be crossing the $200 million mark by Sunday. The repeat customers on this one are off the chain. I would say a $250 million final tally is looking very likely, and, who knows, it’s now not out of the question to believe $300 million could happen.
