Today is June 29th, and if you’ve been living under a rock for the last few days, today’s the day that Apple’s iPhone is unleashed upon the general public.  It also happens to be the day that Disney/Pixar’s newest movie, “Ratatouille”, opens.  Just to make sure that everyone understands the connection, Steve Jobs is the CEO of Apple, Inc., and he was the CEO of Pixar before Disney bought them not too long ago.  Mr. Jobs is currently the largest shareholder of Disney stock.

This leads me to wonder…which of Mr. Jobs “babies” will have a bigger opening weekend in terms of dollars?

According to Box Office Mojo, the biggest opening weekend of all time is “Spider-Man 3” at just over $151 million.  The biggest opening weekend for an animated movie is “Shrek the Third” at around $121.6 million.  The biggest opening weekend for a Pixar animated movie is “The Incredibles” at $70.5 million.

Let’s assume that “Ratatouille” will beat “Spider-Man 3” as the largest opening weekend for a movie and will do so at $155 million (I don’t think it will, but we’re just going to use that as a round number).  For the iPhone to beat $155 million, Apple/AT&T needs to sell 310,000 of the 4GB ($500) model, or 258,334 of the 8GB ($600) model.  Since I suspect that the sales ratio of iPhone models will be 60% 8GB and 40% 4GB, Apple/AT&T needs to sell 155,000 of the 8GB model and 116,000 of the 4GB model, with a grand total of 271,000 combined.

Based on the line at the Apple Store on 5th Avenue, which I can now see from my office on Madison Avenue, I’d say that the iPhone will beat “Ratatouille” in the opening dollars game.
