I believe the answer is:
depict
'show' is the definition.
(synonyms)

'piece of' indicates the answer is hidden within the clue.
'DEPICT' is hidden in the letters of 'hollywood epic theatrical'.
(Other definitions for depict that I've seen before include "Show by drawing" , "'Show, portray (6)'" , "Paint" , "Give a description of" , "Portray, represent" .)
