2) Arthur is all grown up now. He's now a very large, muscular man in which the guards are self aware that he's one of the most dangerous patients in the asylum, but they're more worried about a basketball game to use common sense when opening Arthur's door. Eventually, Arthur murders a few guards and escapes where he goes on a cross country trip to find the actress he fancied for years on television. "For God's sake he can't even drive a car." "Maybe someone around there gave him lessons." 3) The aforementioned actress also has a lot of problems of her own. Her agent wants her to appear in a low budget 'sci-fi, slasher, monster, zombie film. The producer doesn't even know where he wants to go with the movie and has no more money to pay his crew. The beautiful blond actress stops at a gas station where an oversexed middle aged mechanic tries to persuade her into giving in via force. Of course, she resists. A customer pulls in at the right time - The actress runs from the wannabe rapist only to discover that it's a big young man with blood on her face. Old Arthur recognizes her right off the bat. The oversexed mechanic has a change of heart and tries to help the girl, only to be killed by the hands of Arthur. The actress escapes and here we go again.
3) Arthur goes cross country - stealing cars, trucks, and eventually an 18 wheeler. (Keep in mind that Arthur has been locked up ever since he was a kid and can somehow drive an 18 wheeler with 16 gears) The movie takes a turn from familiar slasher territory into a semi-action film with TONS of big-muscular stunt men biting the pavement or desert sand by the hands of Arthur.
4) We see more of the sleazy producer as we're taken to the movie set - right in the middle of the desert. A great location where no one has to be paid for setting up shop in their location. A paradox of the movie itself. Arthur also steals a motorcycle - kills a bunch of muscular buffoons and finally makes his way to the set where he eventually kills the sleazy producer, dresses up in a monster uniform and does his real life gig in front of the camera un announced. After pretending to be an alien monster, he soon gets a little too rough with the actress and his cover is blown. Arthur gets taken down and the rest is history.
