If Inside Out manages to take first this weekend, that would put Jurassic World in a very strange place.
To date, the highest grossing film to only win a single weekend is the final Harry Potter, which did set a weekend record, but then fell to second beneath Captain America's opening.
JW could do the same thing, except it's heading for unparalleled box office heights. It'd be kinda weird.
(#2 on the list is the original Transformers, due to it releasing at 8pm on a Monday.)
