William Ragsdale, Roddy McDowall and Chris Sarandon starred in this hilarious film about the film star "Peter Vincent, The Great Vampire Killer" (McDowall) and his young fan Charlie (Ragsdale) and their fight to save Charlie's girlfriend from a real life vampire, Jerry Dandridge (Chris Sarandon).  Peter Vincent is supposed to be the hero of countless "Hammer Film" type movies and the host of the evening television show, "Fright Night".  When Charlie goes to Peter to tell him the man who has moved in next door is a vampire, Peter naturally doesn't believe him.  Charlie persists and Peter finally goes to the vampire's home with Charlie and his friends to prove to Charlie that Jerry Dandridge is not a vampire.  While there, Peter accidentally learns that Jerry is the real thing.  Although he is terrified, Peter ultimately comes through for Charlie and saves the day.  A good comedy with some great special effects . . . it's a keeper.
