The tale of Hercules and Queen Omphale is taken from the ancient Greek myth, of which there are several variations throughout history. Character names are drawn from a mixture of various Greek legends and plays, notably The Seven Against Thebes by Aeschylus and Oedipus at Colonus by Sophocles. Hercules' line "I wove the threads [of my memory] together" is a reference to his task of spinning thread and weaving with Omphale's attendants. The film is only very loosely based on the source material, randomly mixing events and featuring characterizations varying from those depicted in the sources.
Hercules:
I'm so sleepy, I can't seem to keep awake!
Watch closely the second time Hercules takes up Ulysses' challenge to bend the iron torch stand in an attempt to remember who he is. He successfully does so, and then unbends it just as easily, leaving a slight curve in the stem. However when he returns the stand to its original location, the stand is perfectly straight.
The Italian main title co-credits Iole's song to "Tito Manzese." This was not only a pseudonym, but an anagram of Enzo Masetti who wrote the score.
