Actor Wilson (4)
I believe the answer is:
'actor wilson' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for owen that I've seen before include "Welsh boy's name" , "Wilfred -, English poet killed in World War One" , "Welsh industrialist and social reformer, founder of cooperative communities, d. 1858" , "'E won over the Welshman" , "Clive --, English actor" .)
