NBC's Saturday Night at the Movies opened with GENTLEMEN PREFER BLONDES, followed by THE SNOWS OF KILMANJARO, and third up was TITANIC. Like DRs TCB and RLP - this is the movie and the showing that introduced me to the Titanic saga, and like them I immediately went looking for a book about the ship. Interesting, even though I couldn't find the Sturges family on the passenger list.
NIAGARA was also shown - I think the series started in the fall of 1963, so if was about a year after Marilyn's demise.
