According to this article on the slumping movie business, "aside from "Mission Impossible," none of these movies [in a list of sequels including Superman Returns, Mission Impossible 3, and X-Men 3] can be considered sure things."
Um, HELLO, Robert Walberg?!? Are you blind to the undercurrents of pop culture society?! Tom Cruise = crazy nutjob even wackier than Wacko Jacko according to numerous websites that list such things. MI3 is far from a sure thing.
And X-Men 3 = NOT a sure thing?! What are you smoking?! Sure, Gambit (that spicy Cajun -- and yes, comic characters can be hot) might not be in it, but we all know which summer blockbuster I'll be heading to the theaters for...and here's a hint: it's not one that stars a maniacal couch-jumper.
