Rather than start a new thread somewhere, I thought I would use this to try and clarify something about Karloff's last days - specifically the chronology of his last few performances.

I understand his appearance in The Rules of the Game was his last formal acting role and that he then went back to the UK and died some months later.

However, was Targets immediately before the so-called Mexican quartet or did he make a trip in-between to his mother country to do Curse of the Crimson Altar / The Crimson Cult?

Poor Boris certainly appears much weaker and more tired in that film than Targets.

If someone could confirm the chronology of his last few roles I would really appreciate it.
