This is a complete set of the 451 films that were on the main They Shoot Pictures Don't They list at one time, but that are no longer on the current (2016) list.
Note: These films do not exactly match the order of the list at the TPSDT site because I alphabetized foreign language titles by their whole name. And then some of the titles on Letterboxd differ from those in the list, most often with foreign language ones translated into English. The content of the list should be identical, though. If you feel there is an error, please let me know.
May or may not be on this list when you read it here: The Devil in Miss Jones (1973) because Letterboxd likes to pretend adult films don't exist.
This should be used in conjunction with the 2016 main TSPDT list from Matt Conti:
