Big shot in the film world? (5-2)
I believe the answer is:
close-up
'shot in the film world?' is the definition.
'close up' can be an answer for 'shot' (I've seen this before). I'm unsure of the 'in the film world?' bit.
'big' is the wordplay.
I cannot really see how this works, but
'big' could be 'os' and 'os' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for close-up that I've seen before include "Photograph or film taken at short range" , "Photo giving detailed view, as of actor" , "Shot of small area" , "Short-range photo" , "Near photograph" .)
