1. Sarah Michelle Gellar
Sarah Michelle Gellar, like Nicholas Brendon, has not hit the heights of Buffy the Vampire Slayer since the show came to an end. Again, like Brendon, she has been busy but, apart from Ringer (of which she is both the star and the executive producer), her TV career in particular has been relatively low-key in comparison to her Buffy days. She's been busy on the movie scene (Scooby Doo 2, The Grudge series, Southland Tales), but the majority of her latest offerings have been on limited release or have simply gone straight-to-DVD. Throw Gellar back in to the television limelight and give her one last hurrah as the vampire slaying heroine, even if it isn't for the long haul, or if it's merely a cameo in a spin-off. Millions of Buffy fans would love it.
On a more sombre note, this article is dedicated to the memory of Robin Sachs (Buffy the Vampire Slayer's Ethan Rayne) who died suddenly on the 5th of February 2013.R.I.P. Robin.
