I believe the answer is:

prompt service

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

'appreciated by a forgetful actor' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'speedy help' is the wordplay.
'speedy' becomes 'prompt' (I can't explain this - if you can you should give a lot more credence to this answer).
'help' becomes 'service' (synonyms).
'prompt'+'service'='PROMPT SERVICE'

Can you help me to learn more?

I've seen this clue in The Globe and Mail.
