See these films: Sisters + Twisted Nerve @ the Brattle

Twisted Nerve (1968) opening credits

You might not remember what you've seen in a film with a Bernard Herrmann score, but you'll probably remember what you heard. Like the taunting rhythms of the title music to Sisters (1973; 3:15 + 7:30 pm), Brian De Palma's diabolical thriller about a beautiful pair of divided Siamese siblings who give added meaning to the term "evil twin." Or the creepily chirpy, whistled tune from Roy Boulting's Twisted Nerve (1968; 5:15 + 9:30 pm), the claustrophobic tale of a nice young man in a rooming house who loses it; that music was so unnerving that Quentin Tarantino used it for his Kill Bill. Both films screen as part of the Bernard Herrmann retrospective at the Brattle Theatre, 40 Brattle St, Cambridge | Tuesday, August 23 | $10; $8 students, seniors | 617.876.6837 or brattlefilm.org.
