The Queen of Hearts is physically and verbally abusive to Time and to the servants.

A man is injected with a large needle and collapses.

A girl hits her head on a stone statue, causing it to swell as she falls back in the snow.

Some mild insults and teasing remarks, no swearing.

Alice is nearly injected with heavy drugs at a mental hospital. She manages to grab the needle and inject it into the rear of the doctor, who falls unconscious.

Time is seen slowly dying throughout much of the film's duration; the character appears in a great deal of pain and fear, which may upset some viewers.

The Hatter and the Queen of Hearts are quite grotesque-looking and may frighten younger viewers.

The topic of mental hospitals treating "female hysteria" may offend and frighten some viewers.

Multiple scenes of death and peril, including a fire wiping out a village, characters becoming frozen with red rust, and a man nearly falling from the top sails of a ship (no attempt is made to rescue him).

At the start it is mentioned that Alice's mother sold a ship belonging to Alice's late father to pay for a house. Alice is seen crying.

In Time's castle there are two rooms marked "Underlandians Living" and "Underlandians Deceased" and in each there are pocket watches representing lives. The Deceased room has a night sky while the Living room has a day sky, and Time moves one from living to deceased when their life ends. This representation of death may scare younger viewers.

Part of the premise is that the Mad Hatter is convinced his family is somehow still alive and others unsuccessfully try to get him to accept that the Jabberwocky killed them.

The Hatter, revived, says "you're Alice" while making a creepy face (his irises expand, his eyebrows rise and he grins widely). This may scare younger viewers.
