Ghosts of Mars (2001)

The main female character wakes up in her underwear. She is wearing a tank top and very tight panties. She is seen in her underwear for about 20 seconds before she puts her pants back on.

There's a good many instances; talk, cleavage, caressing, kissing, breeders, but none of it heavy and really long.

A possessed woman has a pair of severed hands covering her breasts, they are tied in a manner to make it appear as if they are groping her.

There's a lot of slashing and a dozen or so cut off body parts. Besides a man slashing his throat, a lady coughing up a huge red cloud, and one slaughter scene that goes on for 1-2 minutes, most of the other heavy gory violence is quick and brief flashes. One gory instance is where a man gets his head, both legs, and one hand cut off at the same time, with blood spraying everywhere. There's a bunch of typical other action violence.

The decapitated head of a woman is shown being stuck on a spike.

Several men are decapitated, though the actual act is done offscreen. Though several severed heads are shown being held by the possessed miners.

Clea Duvall's character is implied to be a lesbian. Some characters use homophobic slurs towards her.

27 uses of "fuck" (4 paired with "mother"), 14 uses of "shit", 19 uses of "hell", 8 uses of "ass" (1 paired with "hole"), 4 uses of "damn" (1 paired with "God"), 2 uses of "bitch", 1 use of "prick", 1 use of "Jesus Christ", 1 use of "Jesus", 1 use of "dike", 1 use of "titty", and 1 use of "piss".

There's a few scenes of drugs and getting high:

A person after having a serious hand injury gets high off some aerosol spray (Statham says its so powerful it'll turn your brain into Swiss Cheese).

A lady appears to be high on something.

The killing is intense. Many of the possessed have metal objects inserted into their skin.
