Underworld was really good fun. I play a vampire called Erika. She's basically the personal assistant to the head vampire in the house, Kraven, und she's a feisty little minx. She's a tomboy, she has no loyalty to anyone, and she's on a mission to take over the whole house. I really enjoyed playing her. It was great fun and a really nice team of people to work with. The film really gave me the chance to do something totally different and be a bit more rock 'n' roll than anything I'd done in the past. I thought it would be quite cool to do an action film, because I'd never done anything like that before. I'm just up for trying different things all the time.

Oh, it was great. I loved working with her [Kate Beckinsale]. It was also great to have another British girl on the set. It was a fabulous experience. And obviously she's a good actress and very beautiful.

I like playing the bad guy. I loved playing the bad vampire when I did Underworld.

Among the supporting cast, at least Sophia Myles, playing Selene’s pouting rival Erika, has 'conniving' down to a science. Combine that with her arresting looks, and she can claim a memorable supporting turn.

The Daily Orange

Among the supporting cast, Sophia Myles ('From Hell') deserves notice for the spunk she brings to the role of vampire vixen Erika. The buxom blonde, a constant foil for Selene, serves as a fun reminder to the audience that all the film's characters, whether hero or villain, are doers of evil.

... and Jealous Blonde Vampire Erika (Sophia 'New Kate Winslet TM' Myles) ...Terrific Supporting Roles... but Myles is good, though her character mysteriously disappears towards the end of the film.

The SF Site

Sophia Myles, as Selene's rival Erika, provides a catty distraction that's kept strictly as a plot device, but watch for the mildly fun scene where she jumps to the ceiling.

The only time that you see one of the vampires fly up and stick to a ceiling is when Erika (Sophia Myles) gets fairly startled to find out that Michael (Scott Speedman) was bitten and is thus a werewolf.
