Film performer’s needs after a walk in the park (4,5)
I believe the answer is:
easy rider
'film' is the definition.
(I've seen this before)
'performer's needs after a walk in the park' is the wordplay.
'performer's needs' becomes 'rider' (I can't explain this - if you can you should give a lot more credence to this answer).
'after' is a charade indicator (letters next to each other).
'a walk in the park' becomes 'easy' (I've seen this before).
'rider' after 'easy' is 'EASY RIDER'.
Can you help me to learn more?
(Other definitions for easy rider that I've seen before include "counter-culture movie" , "Picture" , "Nineteen sixty-nine road movie (Hopper, Nicholson)" , "Film about motor cyclists' travels" , "1969 road movie" .)
