Wacky Ealing comedy’s opening is very innocent (7)

I believe the answer is:
angelic
'innocent' is the definition.
(I've seen this before)
'wacky ealing comedy's opening is' is the wordplay.
I cannot really understand how this works, but
an anagram of 'ealing' is 'angeli' which is within the answer.
A single letter 'c' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'very' acts as a link.
Can you help me to learn more?
(Other definitions for angelic that I've seen before include "Payment for release" , "Divine" , "in the manner of Gabriel?" , "I glance (anag.)" , "Sweet, kind and beautiful" .)
