Juliette becomes one of the first victims of the Thing after it escapes its icy prison; attempting to assimilate Lloyd, her imitation lured the palaeontologist into a secluded room (under the pretenses of helping her find the keys to the station's vehicles). After failing to assimilate her, the imitation goes on a rampage - killing and partially-assimilating Karl before being incinerated by Lars. Following this, the crew of Thule Station become aware of the Thing's ability to imitate other life forms; causing total paranoia among the remains crew.
- She is believed to have a close relationship with fellow Thule Station member Henrik Larsen, as his death seems to have shocked her the most. She is seen grieving and openly expresses her knowledge about the personal facts of Henrik being a family man with two small children.
- Kim Bubbs, the actress who plays Juliette, reportedly almost fainted on set while filming her scene as the Juliette-Thing, when she attempted to scream very loud for a long period of time in order to capture the sound of the creature she was portraying.
- The director did tell her to make some kind of sound, but added that they probably would not use it in the finished movie. However, Bubbs came up with such an impressive demonic growl that it was actually layered into the final mix.
- Juliette was most likely assimilated by the Griggs-Thing, as Griggs watched her run out of the autopsy room and down the corridor, after being deeply disturbed by the sight of Henrik’s corpse. Griggs being already assimilated by this point, saw Juliette's separation from the rest of the group as a opportunity to assimilate her without alerting the others. Another way may be the shower scene where Kate discovers the blood on it. The Thing could have assimilated her while she was in the shower, which could have also been the Griggs-Thing.
- Juliette was the first and only female character in the film franchise to be assimilated by the Thing. Several other women were assimilated, but that happened only in comics.
- Her death was the Golden chainsaw in Dead Meat’s kill count of the movie.
- It’s believed that Edvard was assimilated off-screen by Juliette-Thing
