The dragon wasn't in the original version?

Man, that's insane. Apparently, American International took the film The Revenge of Hercules and shot new scenes involving a dragon because they had promised "Goliath and the Dragon" and ran out of money to make a completely original film.

It's crazy that the focal point of the movie wasn't even in the original cut. I wonder what the dialogue was like the first time around when they didn't have the dragon to talk about.

Timocleo di Medar: With Goliath gone, you've got a hungry jailer in those caverns. That dragon.
King Eurystheus: That's right. No one can stop us.
