Ballet school ought to be disbarred ' By John Stark ; The only thing stranger than the cast of characters In the horror J film "Suspiria" was some of the , X audience at the St Francis Theater, i where I saw it screened yesterday. Z That, however, is another story ; one I found much more interesting than the movie. " "Suspiria," which is also play-; tog at the Serramonte 6 and Metro II. is a violent, blood-spilling movie about witches in a German ballet ; school ("You vill dance or I'll put a hex on your tutu!"). The movie was written and directed by Dario I Argento, whose press biography ' includes a list of his other horror '. films none I've ever heard of. In one scene, a beautiful young dancer is strangled to death while her face is slowly shoved through a glass window. Following that, she's repeatedly stabbed and slashed, then hanged from the rafters. That all takes place in the first five minutes of the film, long before things really get rough. Making a rare screen appearance is veteran film actress Joan Bennett, who plays Madame Blank, a director of the school. All I can say is, Bennett's come a long way since "Little Women," not all of it uphill. Jessica Harper plays Suzy, a young American dancer who learns the terrifying truth about Joan Bennett "Suspiria" is mostly gore, with little plot or intrigue. One thing you have to say these dancers sure have it worse than the kids in "A : 1 1 i 'i Sll&l t 7 f . v i w i Joan Bennett returns to the screen as a witch. Chorus Line." One last question: Since the movie takes place over a several month period, how come the thunder and lightning storm never lets up?
