TCM is hosting a Lumet marathon tonight, which I would like to think of all the memorials and tributes given to the man recently, this is the one he would have probably appreciated the most: Where his movies are shown and be discussed.

8:00 PM 12 Angry Men (1957)
10:00 PM Private Screenings: Sidney Lumet
11:00 PM The Hill (1965)
1:15 AM Network (1976)
3:30 AM Dog Day Afternoon (1975)

Cream of his filmography crop there, with THE HILL a very good little obscure gem of his.
