$100 million was the benchmark of old for what was a blockbuster. These days it's more like $200 million, but $100 million domestic still translates to a "hit." On September 6, The Mummy: Tomb of the Dragon Emperor became the 400th film to reach that milestone. I'm a little late in breaking this... there have been four more since (#401- You Don't Mess With the Zohan: 9/7, #402- Tropic Thunder: 9/12, #403- Step Brothers: 9/13, and #404- Journey to the Center of the Earth: 10/4) and it looks like Eagle Eye at $80 million+ is on its way.
Wonder if we'll make it to 500 by the close of the decade (next year)?
