Show Ben-Hur perhaps in empty depot (6)
I believe the answer is:
depict
'show' is the definition.
(synonyms)
'ben-hur perhaps in empty depot' is the wordplay.
'ben-hur perhaps' becomes 'epic' (Ben-Hur is an epic film).
'in' means one lot of letters goes inside another.
'empty' suggests removing the centre.
'depot' with its middle removed is 'dt'.
'epic' inserted within 'dt' is 'DEPICT'.
(Other definitions for depict that I've seen before include "Illustrate, describe in detail" , "Represent in drawing or painting" , "Show, illustrate" , "'Show, portray (6)'" , "Sketch or describe" .)
