Actor ____ Idle (4)
I believe the answer is:
eric
'actor idle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eric that I've seen before include "--, or Little by Little (Dean Farrar)" , "---- Cantona, Manchester Utd favourite of the 1990s" , "Blair, perhaps" , "Fine" , "..... the Red was Norwegian 10th Century exployer" .)
