... vehicle clip from Terminator? (7)
I believe the answer is:
trailer
I believe this is a double definition.
'vehicle' is the first definition.
(trailer is a kind of vehicle)
'clip from terminator?' is the second definition.
(trailer can mean a clip from a film)
(Other definitions for trailer that I've seen before include "Short film advertising programme" , "Advance ad for film" , "Rear section of an articulated lorry" , "An ad; one towed" , "Towed vehicle; advertisement" .)
