Picture tango, with fellow getting closer (3,10)

'picture' is the definition.
(The Terminator is a film or 'picture')

'tango with fellow getting closer' is the wordplay.
'tango' becomes 't' (phonetic alphabet: alpha, bravo, charlie etc.).
'with' means one lot of letters go next to another.
'fellow' becomes 'he' (I've seen this in other clues).
'getting' is a charade indicator (letters next to each other).
'closer' becomes 'terminator' (something which closes or terminates).
't'+'he'+'terminator'='THE TERMINATOR'
