If the movie does around $50m during the week and $85m next weekend domestically, that puts it at $135m for the upcoming week domestically and boosts it to $810m off of the domestic gross alone. The foreign markets have a good chance of grossing $100m or more if IM3 continues to perform slightly better than The Avengers with the same percentage drop from week 2 to 3. That puts it at $910m for the third foreign weekend. That means foreign weekday numbers only have to come in at around $90m for the film to surpass $1b on Sunday. I don't know if that's possible in the third week though, since BOM doesn't keep track of weekday totals for foreign markets. It's probably not, but still, the film is almost guaranteed to be at most just $80m off from $1b by next Sunday. Crazy.
These films don't just do a billion, they do it insanely fast!
