Leave, on bar, picture (7,3)

I believe the answer is:

holiday inn

'picture' is the definition.
(1942 film)

'leave on bar' is the wordplay.
'leave' becomes 'holiday' (I've seen this before).
'on bar' becomes 'inn' (I've seen this before. I am not sure about the 'on' bit.).
'holiday'+'inn'='HOLIDAY INN'

I've seen this clue in The Times.
