The Arrival (1996, dir. David Twohy)

A disgraced radio astronomer is convinced that alien communications are being received. Quirky SF/horror hybrid with plenty of daft ideas and enough visual interest to keep you watching. No classic, but fun.

Platoon (1986, dir. Oliver Stone)

An idealistic volunteer learns the brutality of war the hard way. Simplistic but undeniably effective Vietnam War morality play, with a soldier’s-eye perspective throughout; an excellent ensemble cast supports the drama.
