According to MovieCollectorOH's amazing database of TCM schedules, Night and the City (1950) was last shown on TCM in December of 2012. (Just learning how to use this.)
I have my own modest TCM schedule data and can confirm that it has not been shown at least as far back as August 2014.
So LornaHF should get credit for having an even better memory than initially thought!
P.S. - I was able to check and Gene Tierney was featured in SUTS for August 1, 2015 and Night and the City was not part of the schedule for that day.
Thanks for this info. It confirms what I posted which was: "Great that TCM secured the rights to the 20th Century Fox film Night and the City".
Because if it has been over 5 years since TCM leased the film, they had to secure the rights again.
