In the novel of Mortal Engines, Katherine Valentine has a pet wolf called Dog. A gift from her father as a young cub, Dog was Katherine's constant companion.
For the film, Dog as been cut as a character. Collider reports:
Fans of the books might be disappointed to learn that Dog, the white wolf animal companion of Valentine’s daughter Katherine (Leila George), was cut from the movie.
“It was a sad day,” George recalls. “I knew about that in the second audition. I came in and I did the audition and they were sitting there like, ‘So, what do you think?’ I’m like, ‘Oh, I really, really love it. I mean, Dog, it would be so cool to have a wolf. I love wolves.’ They’re like, ‘Yeah, there’s no Dog.’ And so I was like, ‘Yeah, no, I hate the dog. That was a really good move.’”
Hugo Weaving recommended having “dog hair all over the couch” in their home, but it was unclear if that made the final script.
