It's not significant - what matters is that on Monday the press covers the "four day total/five day total/opening total" or whatever as some big-ass number which is inflated by the early opening. And when the next big movie opens a week later everyone talks about the "XXX dollar opening of last week's blockbuster" as the point of comparison.

I really don't think Wolverine or T-4 will do so well. Those franchises are old and busted. Star Trek, fresh and new!
