Character mistake: In the final scene at the Mexican gas station there's a sign that says "cigaros" instead of "cigarros," which means "cigars" in Spanish. (01:38:40)

Continuity mistake: When the Terminator arrives at the first Sarah Connor's house, the address number is "14239", even though in the phonebook it is listed as "1823" (or "2816" or "309"). (00:15:15)

Visible crew/equipment: At the end, when Sarah puts her glasses on, a light screen is reflected in them. (01:38:45)

Visible crew/equipment: When Sarah and Kyle have run into the factory, the Terminator is breaking through the armour plated door. As the Terminator comes through you can clearly see the two operator guys crouching behind the model. (01:32:45)

Revealing mistake: When Arnie is being pulled under the semi-truck, his foot is caught and the green-colored dummy leg is revealed. It can't be a special effect sock since green screening was not in practice in the early 80s. (01:23:05)

Continuity mistake: When Kyle and Sarah leave the motel in the pickup, they ram the Terminator before they go, and you can see the bull bars on the front are damaged. When the camera shows the front of the pickup during the tunnel chase sequence, the bull bars are undamaged. (01:20:25 - 01:22:00)

Visible crew/equipment: When Kyle and Sarah escape in the pickup truck, the Terminator chases after them on a red motorcycle. The camera does lots of shots of what's behind Kyle and Sarah and what's ahead of them. When they overtake a truck, you can see headlights following and shining on the back of their pickup. These are the camera crew's lights, as the Terminator's motorcycle is too far away, and previous shots have shown there are no other vehicles around them. (01:21:40)
