For me frowing up "7th Voyage" and "Argonaurts" always seemed to air together on Saturday/Sunday nights on the same station so they will always be tied together in my mind although they are very different films thematically. 7th voyage IS my personal favorite, but critically I'm pretty sure Jason & The Argonauts is the film most recognize as his greatest achievement (of which there were several). After all it's what Tom Hanks referrenced when Harryhausen got his award back in 1992.
Interestingly, although its not a Harryhausen film I didn't see
Jack the Giant Killer until it was on Netflix a couple of years back, which has virtually the same human cast as 7th Voyage.
Also just a fun fact- for the longest time I thought Sinbad & The Eye of the Tiger was some ungodly 3+ hour long movie. The reason was the first time I ver saw it is was on my local PBS station (of all things!). I think it was some sort of TV premier since it was only a couple of years after the film was released theatrically. They kept taking "pledge breaks" which is what made the movie seem so long

.
There are no more good TV Shows, only ones that haven't disappointed me yet.
