Sorry, M or R, but although I'm only *reasonaly* certain that "Targets" was
Karloff's last film, I know "Plan 9" (which was in fact made earlier) was
not.  You're thinking of Bela Lugosi there....

P.S.-- Another good bad one was by "Plan's" director Ed Wood and also starred
Lugosi (all the way through...)--"Bride of the Monster."  And how about "Cat
Women of the Moon" (aka something else I can't recall at the moment).
