What would you consider a blockbuster? 45 million first week on a 3 million dollar budget. Then we have a 50-60 percent drop next weekend. It could push out close to 100 million.

Not talking about just weekend, but total. A blockbuster would be near or over 1 Billion total in the box-office. (Purely my definition.)
