Carthaginian general, an Anthony Hopkins role (8)
I believe the answer is:
hannibal
'carthaginian general' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hannibal that I've seen before include "Great Carthaginian general who led army over the Alps against Rome" , "Carthaginian general who fought Rome" , "Carthaginian general, d.182 BC" , "Carthaginian general who crossed the Alps to defeat Rome" , "Carthaginian general who crossed Alps to attack Rome" .)
