I believe the answer is:

grantham

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

'financial help' is the definition.
The definition suggests a singular noun which matches the answer.

'where a bad actor' is the wordplay.
'where' becomes 'grant' (I can't explain this - if you can you should believe this answer much more).
'a bad actor' becomes 'ham' (a ham is someone who overacts).
'grant'+'ham'='GRANTHAM'

'gets' is the link.

Can you help me to learn more?
