Film featuring cross-dressing little piggy (7)
I believe the answer is:
tootsie
'film' is the definition.
(1982 film)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tootsie that I've seen before include "Part of foot" , "Foot (jocular)" , "Foot or toe - I set, too (anag)" , "Film with Dustin Hoffman" , "A child's foot?" .)
