The actress acknowledged that, although the pair are "very different people", they hare a similar personal transformation.
"Bella and Snow White both come to find that they're leaders. I mean, that's definitely a similarity. They're very, very, very different people," Stewart told SFX.
"Also, everyone's telling them 'No'. And both of them see the light. Both of them are a little more intuitive, and for whatever reason spiritually connected. Their gut is always dead right."
Stewart revealed that her co-star Chris Hemsworth fell into the habit of humming Enya tracks during the making of the fantasy epic.
"He is obsessed with The Lord of the Rings and he was always, like, humming Enya when we were trudging up the mountain," she commented.
"I was saying, 'You should do a remake of Lord of the Rings. Why are you doing this? We're doing Snow White and the Huntsman, Chris!'"
Snow White and the Huntsman will open in cinemas in June, while the Twilight finale Breaking Dawn - Part 2 bows in November.
