Quid Pro Quo et Ultimatum Libido

All these titles have one thing in common, they are actually Latin nouns, names, adjectives or derivates from Latin verbs (with the exception of definite article 'the' that you might not consider and non included swords-and-sandals films like Gladiador (2000), Espartaco (1960) or Quo Vadis (1951), as they are more likely to have a Latin title)
