Film in musical venue (5,4)

I believe the answer is:

annie hall

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

'film' is the definition.
(I've seen this before)

'musical venue' is the wordplay.
'musical' becomes 'annie' (Annie is a Broadway musical).
'venue' becomes 'hall' (I am not sure about this - if you are sure you should believe this answer much more).
'annie'+'hall'='ANNIE HALL'

'in' acts as a link.

Can you help me to learn more?

(Other definitions for annie hall that I've seen before include "Film" , "Picture" .)
