Little short is featuring new actor (4,6)

'little' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'short is featuring new actor' is the wordplay.
I cannot quite understand how this works, but
'short' could be 'curt' (synonyms) and 'curt' is present in the answer.
'is' is within the answer.
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is found in the answer.
The remaining letters 'toy' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?
