Could some familiar faces be heading over to Angel?

E!online's Watch with Kristin columnist cornered various interested parties at the Angel hundredth episode birthday bash, and asked if we could expect any other Buffy cast members to visit LA.

"I know having James Marsters over now has been great for us," said David Boreanaz. "And I'm sure there'll be some other people popping in." Who? "You'll have to wait and see."

Creator Joss Whedon also gave his thoughts:

"Alyson Hannigan obviously was on the show last year, and that was a lot of fun," he said. "We just love having her, and Willow is somebody I'd love to see again on the show. Buffy, you know, that's sort of up to her [Sarah Michelle Gellar]. If she's interested in doing an episode, obviously we'd always make room. There's two guys on the cast who are in love with her, so it's not like she doesn't have anything to play, but it's really her call."

Another person wanting Willow to return is Alexis Denisof (Wesley), but then as Mr Alyson Hannigan he's perhaps a bit biased:

"I think what this show really needs is a redhead," he said. "For me, it's becoming personally offensive that we aren't representing that group. There's only one redhead in Hollywood, so naturally they should hire my wife. I just can't believe there hasn't been an organized movement."
