And as to Star Wars, it didn't even do well in the overseas Market....The Last Episode only made 468 million total overseas. Even Ice Age: Continental drift outgrossed with 715 Million made overseas. Its nice to be overconfident but lets put so realism based on trends.
Comparing the last released Star Wars film to The Force Awakens is ridiculous and ignores all context.
The prequels were horribly reviewed, largely a joke among the existing fan base, in no way managed the cross-generational appeal of the original trilogy.
I'm for sure a huge Star Wars nerd, but unlike "fanbois" I don't give a whit if my favorite property is financially successful or not. I have no feeling or "ownership" in wanting it to do well.
That said, based on the past two weeks, I'd wager it's not only is it going to be the most successful film of the decade, it's completely in the realm of possibility that it's going to knock Avatar off the top spot of all time, since Star Wars will also have the same benefit of the 3D tax included.
The fanbase is what has been awakened - the ones who have been dormant since the 1980's. Have you seen the reactions of folks? I saw an entire office full of 30 and 40-somethings who grew up with Star Wars absolutely transfixed by the trailer - tears in eyes that Han Solo rides again. People that haven't thought about Star Wars in years, who didn't go see a single prequel, who have been re-energized.
The trailer with Han and Chewie was just the tip of the ice berg - some folks had heard "oh yeah, they are making some new Star Wars films, huh?" but it was a far different thing when folks saw that trailer, and it's only going to amp up from here. Heck, there are "reaction videos" to the trailer that themselves have millions of views - the public appetite has just been whet and it's just begun.
Movies that do spectacularly well do so because of a) repeat viewers, and b) cross-generational appeal. TFA has both of these things going for it in an unprecedented way. There are people in their 60's and 70's who will come out just to see the original cast - Harrison Ford alone guarantees that.
If ever there were a film to be "over-confident" about, TFA is it.
