The Manchurian Candidate (1962)

Woman kisses her adult son on the lips. Not played as an unnatural affection, but gross however it's played.

There is a scene involving GIs partying with prostitutes (little nudity, a few bras under half-shirts). In this scene, a GI is seen passionately kissing a woman while moving toward a room. In a later sequence a woman removes her shirt (to her bra); her pants are very short. There is a brief and very discreet "honeymoon" scene with a newlywed couple in bed together (no nudity, just holding hands).

Multiple people are shot; A man is sitting in a chair and is shot; he falls back, bloods spatters all over the wall

Another head shot with visible blood

Other shootings, not as graphic

There is a rough martial arts fight with visible abrasions, and a man is strangled to death on-camera.

Some blasphemy, and about 10 uses of "hell." and a few uses of "damn"

Smoking and drinking are throughout the movie. Two main characters drink champagne and appear drunk.

The shootings can be very intense

There is a long, tense, scary shooting scene

Some intense moments while the story is told through nightmare some of the time.
