besides the fact that some of those movies havent been released yet, its a good idea.
though according to your 'tentative' schedule, the only day that actually fits in a 24 hour period (thats one day for those that are confused) is the last day, and thats if you cut out the closing cerimony and cut each movie to only 2 hours, which at least some of the movies listed are more than 2 hours each. plus i would say have a short break (~10 min) between movies in a trilogy and then a longer break (~30 min) between trilogies. this time used to stretch legs, use bathroom, grab more pizza and beer (or other food if you want, but pizza and beer would be my sole source or nurishment during the trilogy festival)
ideally i think it would be good to have the trilogy festival last 3 days
