Thor: Ragnarok - 26 Easter Eggs & References You Must See

6. Topaz

Frequent Taika Waititi collaborator Rachel House has a small but useful role in the film as Topaz, the Grandmaster's right-hand woman who basically spends most of her time trying to encourage him to be a more brutal leader.

She's actually a comic book character too, though on the page she was a sorceress rather than a flunky. She was a recurring character in Doctor Strange comics, and has traditionally taken two forms - one blonde European and one brunette Indian.

The screen version possesses none of her source's powers and it just seems to be a name plucked out of the comics for the sake of it.
