It is a little after 11 AM and I am pretty much ready for the day to start. Within the next hour people should start arriving and around noon we will start with Star Wars: Episode IV - A New Hope. I will try to update this post throughout the day.
11:55 AM - EPIV starts
1:55 PM - EPIV Done and now lunch
2:50 PM - EPV starts
4:30 PM - Keith arrives with kids and brother and they watch the end of the movie
4:50 PM - EPV ends
5:10 PM - EPIV starts
7:15 PM - EPIV ends and now dinner
8:10 PM - EPI starts
10:20 PM - EPI ends
10:25 PM - EPII starts
12:40 AM - EPII ends
12:45 AM - EPIII starts - I go to bed knowing I won't make it through, others attempt to watch.
3:00 AM or so - EPIII ends, from what I am told (since I was long asleep) Jim made it to the end and the drinkers may have been drifting in and out of consciousness.
8:30 AM - Everyone has now departed to return home, Jim is driving since even at this point we cannot be sure of the sobriety of the other three. At some point today I will watch EPIII myself just to complete the process. I haven't seen it in almost a year when it was in theaters.
9:15 AM - I start watching EPIII
11:40 AM - I finish watching EPIII. I didn't make it through all the movies straight. However if you give me the 24 hours as a Star Wars day I did succeed.
Now the question is what movies for the next marathon. Roger mentioned Star Trek, but I might vote for Die Hard or some other action trilogy.

Posey showing up late? Impossible . . . And why start with Episode IV? You should have gotten Jar Jar out of the picture as soon as possible.
