None. A couple kisses.

A room gets flooded without warning on screen. Nobody is seen inside there since everyone is either on the bridge or the stern.

No violence as of such, however during scenes, panicked members of the ship are seen pushing and shoving each other, some of whom are pushed and as a result slide down the ship to their deaths.

One of the officers can be seen firing a handgun to stop the riot on the Titanic.

A man with the wooden chairs can be seen getting stepped on by people.

One use of 'bastard' (the strongest word used), and a couple uses of 'hell' and one use of the word 'damned'.

Drinks served in the dining and smoking room. The chief baker gets drunk.

One of the first-class women in the lifeboats mentions that it's disgraceful to smoke at a time like this.

The final scene is very intense considering the year the film was made.

The most intense scenes include a couple being crushed by a falling funnel and a few people seen either freezing to death or drowning. A child is brought out of the water dead (though most of the scene is obscured). Most other scenes are psychological.

Really, what hits home is knowing that this is a true story and realising that many people including children died that night.
