Box Office Domestic vs Worldwide The article says that After its fifth weekend the film became the highest grossing sports film ever First it is unclear to me if that information comes from a trustworthy source Second even if the information is true for US domestic gross there are clearly sports films which have earned higher worldwide grosses For example Box Office Mojo reports that Rocky IV 1985 earned a non adjusted worldwide gross of US 300 million Lastly IMDB reports that The Blind Side 2009 has thus far been released only in the USA and Canada hardly a true worldwide release
