More stretch: 1. the Pushkin story on which the opera is based, "Pikovaya Doma" or "Queen of Spades", has as hero an "engineer" named Германн, or "Germann" with a hard G; Lee Harvey Oswald's first girl friend in Minsk, before Marina, also had the last name Германн.  2. WP coverage of "Suddenly", 1954 film starring Sinatra as an assassin who prepares to shoot from a hidden high place, has at times contained disputed claims that Oswald saw that film either in 1954 or 1963. 3. A leading character named "Shaw" appears in both films.  4. It is alleged that Oswald bought the assassination weapon in March 1963, five months after "Manchurian Candidate" was released.
