The Problem with makeing a Movie out of this Myth
Is that it was the Ancient Greek equivalent to a Justice League of Avengers type story, to the Ancinet all of the Argonauts where big Heroes on their own, but Modenr Audiences will mostly only reconise the name of Heracles (And only reconise it's Roman form, Hercules).
In those movie, We barely see the big Herc, and besides him and Jason the rest just seem like Glorifies Extras.
A long length which a new film would likely have could fix some of those problems, but the Problem of Audience Familiarity would still be difficult.
