Professor James Anders (Edward G. Robinson) is an American teacher in Rio de Janeiro who grows tired of working every day, so he retires and puts together a team to pull off a diamond heist during the Rio Carnival: Gregg (George Rigaud) the safecracker, Jean Paul (Robert Hoffman) the playboy, Agostino (Riccardo Cucciolla) the electronics expert and Erich (Klaus Kinski) the military man.
Standing in their way is the Grand Slam 70 security system, an alarm that uses microphones to detect any sound. Can they successfully seduce the girl (Janet Leigh), get the key, rob the safe and get out alive? And what if one of them isn’t willing to share the loot? How does Adolfo Celi fit in?
The only other film by director Giuliano Montaldo I’d seen before was the Closed Circuit. This caper film moves quickly and has a great closing scene. It was written by Mino Roli, Augusto Caminito and Paolo Bianchini along with Marcello Fondato, José Antonio de la Loma and Marcello Coscia. It took more writers to do the script for a caper movie than crooks to pull the caper!
The Kino Lorber blu ray release of Grand Slam has commentary by Howard S. Berger, Steve Mitchell and Nathaniel Thompson and a trailer.
