How angler is starting search for aerial stunt actors? (10)

'how angler is starting search for aerial stunt' is the definition.
I can't tell whether this defines the answer.

'actors?' is the wordplay.
I cannot really see how this works, but
'actors?' could be 'cast' (group of actors) and 'cast' is found within the answer.
The remaining letters 'flying' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
