Chart order 

At the moment the budgets are charted off the IMDB amounts.  It seems silly to arbitrarily select a source for the chart order, expecially when there are concerns noted above over the site being a reliable source.  As you can see I've been working through the films adding reliable sources from places like The New York Times, Variety etc, so there is now better sourced information to rank the films from.  

Given the nature of budget estimates, they often differ from source to source and that has to be taken into account.  I'm against arbitrarily 'picking' a source to rank by.  I am also against the idea of averaging the amounts given by the sources or picking the most frequently cited amount, since this system would be open to manipulation by adding more sources.  My solution would be to rank using the lowest common denominator; case in point:  some sources say GI Joe cost $170m, and some $175m, but while the figures don't match they both agree that the film cost at least $170m.  In view of that, my suggestion would be to rank off the lower amount, but include the higher amount as an alternative estimate.  In the case of films where we have an official figure I'm of the opinion that the films should always be ranked by the official budget with any further estimates included as an alternative estimate.

I'll hopefully finish sourcing the remaining films on the chart over the next week and will then implement the new chart structure if no-one has any objections.
