Crunching the Disney-Star Wars numbers: Disney's (DIS -1.6%) purchase of Lucasfilm wasn't cheap, but it could also pay for itself quicker than early estimates. The last three Star Wars movies brought home $2.5B - a mark which seems easily attainable by the upcoming three with higher ticket prices, IMAX, 3-D, and the Disney marketing machine all working in the favor of a revenue bonanza. Also in the mix: 1) Stand-alone Star Wars movies. 2) Live-action TV series. 3) Gaming revenue opportunities. 4) New initiatives tied to Star Wars branching out to Disney theme parks and merchandising.
