Movie giant you wouldn't want to ape (4,4)

I believe the answer is:

king kong

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

'to ape' is the definition.
(I have seen 'Fictional ape ' mean 'king kong' so perhaps 'ape' could also mean 'king kong')

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for king kong that I've seen before include "Eponymous giant ape in movie" , "Monster ape of early cinema" , "Fictional ape" , "Giant ape of fiction" , "Great ape of film" .)

I've seen this clue in the Evening Standard.
