A few more...

17. The Big Sleep. Classic noir thriller, with the added twist that Humphrey Bogart and Rita Hayworth's on-screen chemistry was buttressed by their off-screen interest in one another.
18. Maxed-Out. A mediocre documentary about the nation's debt problem. Alternates too much between the nation's debt problem with the issues facing people who are having a hard time avoiding bankruptcy. Some lessons between the groups are similar, but the causes are disparate that there aren't very many good take-aways from the movie.
19. Baader-Meinhoff Complex. The true story of the German terrorist group Baader-Meinhoff who tried to incite a socialist revolution in the 60's and 70's. Some of the most interesting parts of the movie are watching the members of the "Complex" alternatively either completely out of their element (such as their training in Lebanon) and their passionate conviction in their cause when they were behind bars.
20. The 39 Steps. A rom-com disguised as a thriller. While there's quite a bit of intrigue in the first half, and a very satisfying ending, the second half seemed plodding because of Robert Donat and Madeleine Carroll's cute little tussles as a couple that finds themselves literally shackled to one-another.
