Film kids walking by brown river (9,6)

I believe the answer is:

crocodile dundee

'film' is the definition.

'kids walking by brown river' is the wordplay.
'kids walking' becomes 'crocodile' (informal term for a line of people, esp. children).
'by' is a charade indicator (letters next to each other).
'brown' becomes 'dun' (dun is a kind of brown).
'river' becomes 'dee' (River Dee).
'crocodile'+'dun'+'dee'='CROCODILE DUNDEE'

I've seen this clue in The Guardian.
