This Giant Papier Mache Boulder Is Actually Really M

Three ordinary guys suddenly get sucked into an old b grade sci-fi movie and set out on a perilous adventure to try and get back home. This is a low budget universe of kooky looking robots, exaggerated characters, evil warlords, amazons and giant lizards. It may look fake but it will surely kill you if you don't watch out. And when one of the three strangely starts to change into a sci-fi character. If they don't find an answer soon they will all be lost in this crazy place forever.
