Many characters are attracted to others they are not married to. A couple, one of whom is married to someone else, kiss a couple of times. A character drops their trousers to retrieve a hidden object. Some topless men.

Very little. One character fires a pistol at another and attempts to club them with it. A doctor talks of patients killed or dying.

This is not Chekhov's script. Fuck and piss or derivatives are used a few times. Characters discuss the hopelessness of their lives with reference to God.

Characters drink alcohol to the point their behaviour is affected; almost exclusively vodka. One character smokes. A doctor discusses drugs he carries with him. A bottle of morphine is missing at one point, with reference to suicide as a motive for stealing it.

No.
