How many lines did Arnold have in T1?
Arnold’s voice is used in exactly 16 lines, with 17 sentences spoken. The Terminator has two other lines, one with the voice of a police officer overdubbed, and one with the voice of Sarah’s mother overdubbed. There are also many lines with the voice of Sarah’s mother, and we learn that the Terminator is actually saying them, but we don’t see it onscreen.
