And what does Arnie say at the end of the Spanish version of Terminator?
____________________________________________________________

There are two Spanish versions of Terminator. In the Latin American Spanish version, the phrase remains, as it is, with an expression in Spanish. However, in the European Spanish version, it changes to “Sayonara, Baby” (“Sayonara” in Japanese means “Goodbye”). The reason for this change is that the phrase must be pronounced in another language, otherwise its meaning is lost.
