Wrongly accused, as one hopes those leaving theatre have been (8,2)

I believe the answer is:

stitched up

This clue is a double definition.

'wrongly accused' is the first definition.
(to stitch someone up is to frame them)

'as one hopes those leaving theatre have been' is the second definition.
(as in an operating theatre)

I've seen this clue in The Guardian.
