During the wedding night sex scene, the husband touches the wife through clothing. There is no male or female nudity.

Monster comes to life and is held up with chains while he is naked with full frontal view - penis and pubic hair exposed.

The wedding night scene is long and somewhat passionate, but there is no nudity.

There are a couple of passionate kisses and a wedding night scene in which the couple loosen each others' clothing and it's implied that they make love after the scene cuts.

Dr. Frankenstein marries a woman who was adopted by his family and raised as his sister. Yeah, it was a different time back in the day, folks.

When the Monster first lives, male nudity is shown (his backside along with some brief frontal images)

No female nudity is shown.

The creature bumps a man on a door.

A woman gives birth and dies. Blood is seen.

There is a part where autopsy on a human is shown mostly offscreen. Nothing graphic.

The monster attacks and kills a person, pulling out the victim's heart with bare fists. The very bloody corpse is shown.

Someone commits suicide by holding a lamp overhead and breaking it, becoming engulfed in flames (not gory but extremely unnerving).

The monster has a lot of stitches and scars on its body.

A person is killed offscreen. We hear flesh tearing (nothing is shown).

A kid came across the Monster and later runs away but killed offscreen.

A few mild profanities and insults.

None

It has some less frightening, but mostly very emotional scenes.

Severe

A woman burns herself alive and dies

Victor revives Elizabeth but her appearance was hideous due to stitches and scars left on her.

Multiple jumpscares

The monster looks frightening

The film is a very sad tale of men unable to accept the Creature because of his appearance
