The Apartment (1960 Billy Wilder)

This is quite quickly cut too, though there are distinctive long takes like Jack's attempts to rearrange his calendar, cooking.

I laughed when I realised he gives his name right at the beginning as 'Bud' - thus the ensuing 'Buddy-boy' is even funnier.

Am always a happier man after this film, which isn't sentimental at all.
