Wizards of the Lost Kingdom
Another adventure in a "lost world/kingdom/etc". Awesome cheesy fantasy movie with more side quests than an Elder Scrolls game. This one is begging to be riffed.
The thing is they actually riffed it before Joel and Jonah did. Sadly, it's joined the ranks of Riff In Peace but I'll give you some votes in the hope it will get their riff back up.
