Cruise by Hollywood location after box office draw (7)
I believe the answer is:
tombola
'draw' is the definition.
(prize draw)
'cruise by hollywood location after box office' is the wordplay.
'cruise' becomes 'tom' (actor Tom Cruise).
'by' means one lot of letters go next to another.
'hollywood location' becomes 'la' (Hollywood is part of Los Angeles).
'after' says to put letters next to each other.
'box office' becomes 'BO' (entertainment industry acronym).
'la' put after 'bo' is 'bola'.
'tom'+'bola' is 'TOMBOLA'.
(Other definitions for tombola that I've seen before include "Game played at fetes" , "Ticket-drawing game" , "fund-raising event" , "Lottery in which tickets are drawn from a revolving drum" , "Lottery with a rotating drum" .)
