Corrected entry: At the end of the movie Teddy is sitting on the steps of the building and Chuck approaches, sits with him and offers him a cigarette, and takes one himself. As Chuck takes his out of the pack of Lucky Strikes the cigarette has a filter. Lucky Strikes did not have filter cigarettes in the 1950s.

Correction: Watch the scene again. It is a plain white, unfiltered cigarette. The best view is at 2.02.53 when the cigarette is visible, framed against Andrew/Teddy's dark blue trousers.
