Flipping focus to watch sailor boxing CGI-produced lion, say (3,3)
I believe the answer is:
big cat
'lion say' is the definition.
(lion is a kind of big cat)
'flipping focus to watch sailor boxing cgi' is the wordplay.
'flipping' is a reversal indicator.
'focus to' indicates the central letters (focus can mean the centre of something).
'sailor' becomes 'ab' (abbreviation for able seaman).
'boxing' is an insertion indicator ('box' can mean contain, as in to put in a box).
The middle of 'watch' is 't'.
't'+'ab'='tab'
'tab' enclosing 'cgi' is 'tacgib'.
'tacgib' in reverse letter order is 'BIG CAT'.
'produced' is the link.
(Other definitions for big cat that I've seen before include "One may have pride" , "ounce, say" , "'Tiger or lion (3,3)'" , "Eg, Lion or tiger" , "Lion or tiger, say" .)
