Yes Brydo that’s the “Official Secrets” one with Keira Knightley, it is on for the second week at the Showcase Glasgow (near Coatbridge/Uddingston) until Wednesday, but only at 10.50pm now, or at Cineworld Glasgow at 11.00am or 7.30pm tomorrow. You may find it else-ware, these are the two that found.
By the way the Showcase Glasgow if you have not been recently, is a Deluxe Cinema with leather (or leatherette) reclining luxury seats and room for wheelchairs at the back row, but not ideal for snogging. It also has loads of disabled parking. Their Paisley Showcase Cinema is almost identical but with a different list of films.
But with your political interest/views, it’s a film you must see and one I assume your good wife could also enjoy.
