Road movie? I had little hesitation after years at sea (4,5)
I believe the answer is:
easy rider
'road movie?' is the definition.
(Easy Rider is a road movie)
'i had little hesitation after years at sea' is the wordplay.
'i had' becomes 'id' (I'd).
'little hesitation' becomes 'er'.
'after' means one lot of letters go next to another.
'at sea' indicates an anagram.
'years' with letters rearranged gives 'easyr'.
'id'+'er'='ider'
'ider' after 'easyr' is 'EASY RIDER'.
(Other definitions for easy rider that I've seen before include "counter-culture movie" , "1969 road movie" , "Picture" , "Nineteen sixty-nine road movie (Hopper, Nicholson)" , "Film about motor cyclists' travels" .)
