Disney has kicked off the ticket distribution of the special free IMAX 3D preview of Tron Legacy. Simply go to tronnight2010.com and select your city. You’ll want to hurry as showings are already selling out. The preview will last for twenty minutes, however the tickets state that you must get to the theater at least one hour ahead of time or else your seats will go to people in the standby line. Also, Disney was smart with this arrangement as the ticket has your name on it and it will be checked against a list at the theater; so no eBay scalpers! Each ticket is good for admission for two people, so get clicking!
