330 million worldwide is a flop?

Agreed, Just annoying how it's written as a "flop" like everywhere. It'd be 1 thing had it only grossed 25 million in the USA or say 80 million worldwide.

You don't hear much about this film. From what you can read online, it was supposed to be the next Pirates Of The Caribbean. It grossed a lot of money internationally, but domestically it only grossed $90 Million from a $200 Million Budget, so a lot of films are considered a box office flop if they did not exceed the budget domestically, even if they did internationally. Like, if you look at a film I remember as a kid, Dante's Peak it says on IMDb, it has the keyword Box Office Flop when it also didn't exceed the budget domestically, but internationally.
So, this film was again supposed to be the next Pirates Of The Caribbean franchise. If they earned a lot of money, there obviously would have been sequels, but it looks like they won't be making sequels. However, 2 weeks after this movie came out there was the new Karate Kid with Jaden Smith which had a lower budget of $40 Million and earned $176 Million Domestically. Since that movie did so well, they've been planning on making a sequel and we're just waiting for it to happen which shows the difference between a movie that does earn a lot of money, and one that doesn't.

Great point.

But why did it flop?

I remember seeing this movie with two of my friends when it came out 5 years ago. The movie was cool, but hard to understand. I mean they tried to do a good job and make it like the new Pirates Of The Carribbean, but it didn't work. I don't think either of my friends really cared for the movie when we saw it. I haven't seen the movie since, and I remember hearing a group of guys say at the movie theater a few weeks later how this movie was advertised pretty well, but it wasn't that great of a movie.
