Now some of you may be asking "What film is our interpid little movie-goer
attending that has got him so awestricken?". Well in the previous example, he
has saved his allowance for month eagerly awaiting Star Wars. But perhaps he
could be viewing Planet of the Apes and has reached the climactic the climactic

just started pouring out of the elevators. Or maybe he bought a ticket for
