This summer was a very profitable one for box offices nationwide, with four movies grossing over $300M, and at least another nine grossing over $100M -- signaling in a big way the resurgence of the movie industry, which had been struggling for the last few years.

The four big $300M+ winners of the summer were Sony Corporation (ADR) (NYSE: SNE) 'sSpider-Man 3, which grossed $336M in the U.S., Viacom, Inc (NYSE: VIA)'s Paramount's Shrek the Third, which grossed $320M, Transformers, also from Paramount, which grossed $311M, and The Walt Disney Company (NYSE: DIS)'s Pirates of the Caribbean: At World's End, which grossed $308M.

Three of the four were third installments of well established big-budget franchises, so their success is hardly shocking, but the Transformers success clearly marks the start of a new blockbuster franchise (the release date of the sequel has been announced -- June 26, 2009). The robot-action extravaganza, which was directed by Michael Bay, was definitely a surprise, as I remarked in my summer movie preview that Transformers "has flop written all over it... there cannot possibly be enough substance in a story about alien robots that transform into vehicles to make this a hit with the general public." I was wrong -- very wrong. The movie killed at the box office, grossing over $330M on a $150M budget, and prompting a re-release on IMAX, which opened last week.
