Supernatural gets some Buffy guests

James Marsters and Charisma Carpenter (Spike and Cordelia from Buffy The Vampire Slayer and Angel) have signed on to guest star in the next series of Supernatural.

The cult TV stars will appear in the fifth episode of series, Shut Up, Dr Phil, in which Carpenter plays a witch living in a small town with her husband (Marsters) when she incurs they wrath of the local citizens.

It's not the first time Supernatural has seen Buffy veterans appear in the popular spooky drama. Angel star Amy Acker (Illyria) cropped up in the first series episode Dead In the Water as a woman with a dark secret; Buffy's Amber Benson (Tara) played a vampire in the second series adventure Bloodlust; and Angel's Mercedes McNab (Harmony) - now starring in Adam Green's Hatchet 2 - also bared some fangs in the third series episode Fresh Blood.

Since Buffy and Angel ended, the big stars of those shows have certainly spread their wings, claws and stakes. David Boreanaz is filming a seventh series of the brilliant Bones; Alyson Hannigan continues to make us laugh in How I Met Your Mother; and our very own Anthony Head - who appears in The Inbetweeners Movie - will next be seen in a US version of Channel 4's Free Agents.

Meanwhile, Sarah Michelle Gellar's new series Ringer - which is co-created and co-produced by Supernatural vets Nicole Snyder and Eric Charmelo - has been snapped up by Sky Living.

The drama, about a trouble woman who assumes her dead sister's identity to escape the mob, is set to premiere in the US in September, and shortly after in the UK.
