I believe the answer is:

easy rider

I'm a little stuck... Click here to teach me more about this clue!

'cult film's' is the definition.
'easy rider' can be an answer for 'film's' (I've seen this before). I am not sure about the 'cult' bit.

'undemanding added condition' is the wordplay.
'undemanding' becomes 'easy' (synonyms).
'added condition' becomes 'rider' (I've seen this before).
'easy'+'rider'='EASY RIDER'

Can you help me to learn more?

(Other definitions for easy rider that I've seen before include "Nineteen sixty-nine road movie (Hopper, Nicholson)" , "Peter Fonda film" , "Picture" , "1969 road movie" , "Film about motor cyclists' travels" .)
