Cinema -- cool, funny, cheap (10)
I believe the answer is:
economical
'cheap' is the definition.
(I've seen this before)
'cinema cool funny' is the wordplay.
'funny' indicates an anagram.
'cinema'+'cool'='cinemacool'
'cinemacool' with letters rearranged gives 'ECONOMICAL'.
(Other definitions for economical that I've seen before include "Inexpensive" , "Money-saving" , "saving money" , "Thrifty" , "Giving good value for money" .)
