More theatrical, one pitching a tent? (6)
I believe the answer is:
camper
This clue is a double definition.
'more theatrical' is the first definition.
(camp can mean theatrical)
'one pitching a tent?' is the second definition.
(someone camping)
(Other definitions for camper that I've seen before include "Tent resident" , "Person under canvas" , "Van in which to live on the road" , "Holiday vehicle" , "Holidaymaker with tent" .)
