I believe the answer is:

goldeneye

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

'movie' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.

'information about hackneyed detective' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'about' indicates putting letters inside.
'hackneyed' becomes 'old' (I've seen this in another clue).
'detective' becomes 'eye' (as in a private eye).
'gen' going around 'old' is 'golden'.
'golden'+'eye'='GOLDENEYE'

Can you help me to learn more?

(Other definitions for goldeneye that I've seen before include "spy film" , "Northern diving duck - 1995 Bond film" .)
