I've compiled the cast credits for all 8 episodes of
Odissea, but the sort of leave me scratching my head. They are fairly sparse, especially for episodes 7 and 8 where no one but Bekim Fehmiu and Irene Papas are credited. Interestingly, the credits differ from those printed in Radiocorriere TV, even though those credits tend to be pretty identical to the on-screen ones. Radiocorriere actually list several actors who are not credited on-screen, but sometimes list them in the wrong episodes it seems, so it's pretty messy. It's possible that the series originally had additional cast credits at the end of the episodes, because the version on Raiplay has Italian opening credits, but English end credits, which has presumably replace the original Italian end credits...
Anyway, here are the credits:
Episode 1 on-screen credits + Radiocorriere TV listing
Episode 2 on-screen credits + Radiocorriere TV listing
