In a way FYEO was a remake of FRWL... decoder and all.
I don't think so. Both FRWL and FYEO deal with decoders. In the 1963 film, Bond is being set up by SPECTRE to steal the Lektor from the Soviets - using Tatiana as bait. In the 1981 film, Bond has to find the missing ATAC decoder (which is British) before the Soviets can get their hands on it . . . and deal with a vengeful Melina at the same time.
Like I said, although both movies deal with decoders, each has a completely different plot.
But there are, arguably, other similarities:
-The villains set up Bond to do their dirty work for them then trying to kill him as they plan to make off with the goods
-A blond henchman tries to kill Bond in both films; Loque never speaks and Grant doesn't speak until the final third of the film
-Bond has older partner who helps him, Kermin in FRWL and Columbo in FYEO
-The main heroine shoots a villain to save Bond's life
-Large-scale fights with extras in which a villain is shot at the climax
-Both films had scenes shot in Italy
-Tatiana Romanava is used as bait for Bond to get the Lektor and set Bond up to be killed; Melina is used as bait in Cortina to kill her and Bond
-Bond is set up to be executed in both films
-Bond is betrayed by someone who is supposed to be an ally in both films
-Walter Gotell is in both films working against Bond
