School where sci-fi film is being shown? (4)
I believe the answer is:
eton
'school' is the definition.
(famous UK public school)
'sci-fi film is being shown?' is the wordplay.
'sci-fi film' becomes 'et' (E.T. the Extra-Terrestrial).
'is being shown?' becomes 'on' ('on' can mean broadcasting on TV).
'et'+'on'='ETON'
'where' is the link.
(Other definitions for eton that I've seen before include "Independent school" , "College in Berkshire" , "English college of note" , "Public school founded by Henry VI" , "College, collar or crop" .)
