Where Did The Extra 7 Minutes Of film come from?

I distinctly remember Ridley saying this "Cut" of the film came in at roughly 1 Hour and 59 Minutes, but for the cut of the film at the MAX theater I am going to in Montreal, it is listed as 2 hours and 6 minutes. Does any body have any ideas for me on the reason for the discrepancy in film length?
