'film' is the definition.
(1988 film)

'screened involving popular old woman' is the wordplay.
'screened' becomes 'ran' (I can't explain this - if you can you should believe this answer much more).
'involving' is an insertion indicator.
'popular' becomes 'in' ('in' can mean trendy).
'old woman' becomes 'ma' (both can mean someone's mother).
'in'+'ma'='inma'
'ran' enclosing 'inma' is 'RAIN MAN'.

Can you help me to learn more?
