Is it possible to predict how much buzz a movie opening will get based on the buzz three days before it opens? Using BlogPulse, Nielsen Online’s free tool that mines data from over 78 million blogs, I queried two recent movie premieres (Iron Man and Speed Racer) and one about to open today (Indiana Jones And The Kingdom Of The Crystal Skull).

The results are interesting, showing that buzz levels for each movie seem to be equal as they spike and decline in the days before and after the opening. Does this pattern hold true for all premieres? Three days before the premieres of Iron Man and Speed Racer their buzz levels began to spike and eventually tripled on opening day. Iron Man went from 0.182 to 0.486 percent of all blog posts and Speed Racer went from 0.055 to 0.195 percent of all messages measured by BlogPulse.

The buzz level for Indiana Jones three days before was 0.273 percent of all messages. If the theory holds true on opening day, we will see the spike for Indy triple to somewhere in the 0.8 percent range… well beyond Iron Man which has been the biggest blockbuster this year. We’ll check back next week to compare the buzz and the box office for Dr. Jones.
