'At any cost') is a 1967 heist film directed by Giuliano Montaldo and starring Janet Leigh, Robert Hoffmann, Klaus Kinski, Riccardo Cucciolla, George Rigaud, Adolfo Celi and Edward G.

Bored with years of teaching, Anders retires and sets about putting together a team to pull off a diamond heist during the Rio Carnival in Brazil.

With the help of a youthhood friend, now a successful criminal, Anders recruits a team of four international experts to carry out the robbery: Gregg, an English safecracking specialist; Agostino, an Italian mechanical and electronics genius; Jean-Paul, a French playboy (whose job it is to seduce the only woman with a key to the building holding the diamonds, the lovely Mary Ann); and Erich, a German ex-military man.

However, the following day the police are alerted by Mary Ann, who has found that the safe key had been temporarily taken, and all the four members of the team are killed during their escape.

Anders ends up with the diamonds in a small letters case, sitting in an outdoor cafe, but loses them in Rome to a thief gang on a motorcycle.
