Ok some more tips...bored at work
The Godfather Trilogy (of course 3 doesnt come close to 1 and 2).
Or instead of a trilogies why not have a Robert DeNiro marathon (ie. Godfather 2, Casino, Goodfellas, Raging Bull, etc.)
If you're into Anime then why not Ninja Scroll, Princess Mononoke, Spirited Away! One of the best shows around is Samurai Champloo (hilarious with a great story line). Again, if you like anime then rent Samurai Champloo, Ghost in the Shell 1/2 or the series, and Appleseed for a QS8 workout.
Also, we had a marathon with the Spawn Ultimate Collection animated series (not to be confused with the lame Hollywood movies). This show used to air on Showtime or HBO and flat out rocks. It is definitely more adult themed so no kids. Starts out slowly in season 1 but gets REALLY good in S2 and 3. You can buy all 3 seasons for about $20-30 (great bargain)!
Once Upon A Time in China could also be considered. Or pretty much any TV show you like but those seasons can get long with hour long dramas.
I think you have more than enough suggestions from me and these will keep ya busy for a while to come.
