Informed -- as is a film actor? (2,3,7)
I believe the answer is:
in the picture
'informed as' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'film actor?' is the wordplay.
I cannot really see how this works, but
'film' could be 'picture' ('picture' can be a synonym of 'film') and 'picture' is found within the answer.
The remaining letters 'inthe' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'is a' is the link.
Can you help me to learn more?
(Other definitions for in the picture that I've seen before include "stars' location" , "well-informed" , "Fully informed" , "like the shutterbug's subject?" , "Well briefed" .)
