Some speculate that JFK's assassin might have been brought into the USA in a similar way, that is if you don't accept that Oswald was the lone gunmen. This film was made in 1962 & JFK was asassinated in 1963. The Manchurian Candidate was also made in '62 & that film was out of circulation for many years due to it's connection with JFK's asassination. kreepy.
shareThat is incorrect. Manchurian Candidate was aired on CBS twice in the 60's and on NBC twice in the 70's. It did get less airplay than other films of its stature, but most agree today that that was because of contract issues.
Aside from the idea of political assassination, Manchurian Candidate has little to nothing in common with the Kennedy assassination. So, to address your conclusion: no, not "kreepy".
