Location of a projected entertainment (6)

I believe the answer is:

cinema

I'm a little stuck... Click here to teach me more about this clue!

'entertainment' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for cinema that I've seen before include "Movie theatre" , "Movie house" , "Where films are shown" , "Motion pictures" , "Film industry" .)

I've seen this clue in the Evening Standard.
