During Daphne's 'Train Party' there are a lot of bare legs on display when all the girls decide to join in. All feet are also bare, and whilst fairly innocent today, these were body parts generally covered up in films made prior to the 1960s.

Marilyn Monroe lies on top of Tony Curtis on a couch while they make out with each other

As always, Marilyn Monroe is a very sexy character.

Sex comes up in dialogue. It's played for laughs.

Marilyn Monroe's cleavage is seen numerous times.

A woman wears an outfit in which her breasts are pretty much completely bare. At 1h 6mins into the film, lasts some 15-20 minutes. And again at 1h51.

Scenes of two characters making out on a couch. Very sensual scene and some people may call It a clothed sex scene.

Characters frequently scantily clad.

Some sexual innuendo and play with sexual identity in the dialog.

Humor is often based on sexual confusion and comic sexual situations

Comic verbal innuendo

At one point a man (desguised a woman) has an erection.

Three violent scenes. First is assassins lining up thugs and shooting them with machine guns. The second is one man shooting several others(the bloody aftermath is shown). Third is a car chase with people being shot.

A car chase with cops and criminals. A couple people are shot in the head. Several cars crash and people shoot at each other for long periods of time.

Most, if not all of the violence happens in the first half.

A machine gun shooting of various characters. We see guns open fire one several people. A man with a bullet hole in his back is shot lots of times and we see his somewhat graphic corpse. Several people are shot before this. Read the other part of violence and gore to hear more.

Some crass expressions.

Sugar is an alcoholic.

Frequent adult drinking and especially smoking.

The shootings are intense but more or less played for laughs.

The saint Valentine's Day massacre may upset some viewers.
