Titanic is still King of the World and the rest is dominated by franchises. I hadn't realised the Harry Potter and Pirates of the Caribbean series had been quite so succesful.

The most recent movie on the to make the top 30 is:

28.Indiana Jones and the Kingdom of the Crystal Skull (2008) $714,884,000

Despite it's flaws (check out Chisholm's review on the site here) this success at the box office will no doubt lead onto more in the series...Mutt Jones and the Flash in the Pan anyone?
