What film missing first broadcast on TV channels suggests drink? (4,6)

I believe the answer is:

malt whisky

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

'drink?' is the definition.
(malt whisky is a kind of drink)

'what film missing first broadcast on tv channels' is the wordplay.
'missing first' means to remove the first letter.
'broadcast' is an anagram indicator (letters scattered or cast around).
'on tv channels' becomes 'sky' (I can't justify this - if you can you should believe this answer much more).
'film' with its first letter removed is 'ilm'.
'what'+'ilm'='whatilm'
'whatilm' is an anagram of 'maltwhi'.
'maltwhi'+'sky'='MALT WHISKY'

'suggests' acts as a link.

Can you help me to learn more?

(Other definitions for malt whisky that I've seen before include "Distilled spirit" , "nightcap" .)

I've seen this clue in The Independent.
