Since 2004 Whedon has been working on other projects, such as "Serenity", "Wonder Woman" and "Astonishing X-Men". However he has approached people and asked if they would be interested in participating in the Spike movie. He has said that Amy Acker would be a part of the movie, and if Alyson Hannigan was available she might appear. Whedon has even mentioned he might interlink the Spike story with that yet to be told in "Buffy" comics he will be writing for Dark Horse in 2007.
