Sherlock Jr (1924)/Death On The Nile (1978)
Seen as a double feature, both were great but Sherlock Jr left a better impression on me. Seeing it with a live organ accompaniment was also a plus.
Twilight’s Last Gleaming (1977)
Excellently tense and paced, maybe Robert Aldrich’s best work. I’d say I liked it more than The Dirty Dozen, although it was kind of unintentionally funny to see American soldiers use a german WWII era Jagdpanzer.
