Box office analysts are suggesting that this weekend's debut of Mission: Impossible 3 will provide some indication of what the summer season holds in store for the industry. They note that the film has everything going for it -- a recognizable franchise, the star power of Tom Cruise, decent-to-excellent reviews, and 4,054 screens (170 of which are digital), making it the fourth-widest opening in history. Its predecessor, M:I2, grossed $57.8 million over the first three days of the Memorial Day weekend in 2000. Analysts have low expectations for the other two films opening this weekend, the kids-oriented Hoot, and the horror film An American Haunting. Also debuting in limited release is the Chinese epic, The Promise, the most expensive film ever produced in that country (and a blockbuster hit on the Chinese mainland).
