Films attempt to make a wall hanging (8)
I believe the answer is:
tapestry
'a wall hanging' is the definition.
(I know that tapestry is a type of wall hanging)
'films attempt to' is the wordplay.
'films' becomes 'tapes' (I've seen this in another clue).
'attempt to' becomes 'try' (I've seen this in other clues).
'tapes'+'try'='TAPESTRY'
'make' is the link.
(Other definitions for tapestry that I've seen before include "Fabric picture" , "Decorative hanging" , "Heavy ornamental fabric" , "Complexity" , "Embroidered wall hanging" .)
