Ever since the cult zombie classic Shaun of the Dead hit theaters exactly 10 years ago, many fans have been clamoring for a sequel. While that won't be happening anytime soon, Simon Pegg announced today on his Twitter page that he will reprise his role as Shaun, with Nick Frost returning as Ed for Phineas and Ferb's Halloween special on the Disney Channel this October.

Of course, it isn't known how these beloved characters Shaun and Ed will fit into the Phineas and Ferb story, but the series has a long history of referencing hit movies since the show first started airing on the Disney Channel back in 2007. The show has referenced hits such as Star Wars, Star Trek, Indiana Jones, E.T. the Extra-Terrestrial, Frankenstein, The Lord of the Rings, My Fair Lady, The Little Mermaid, Monty Python and The Holy Grail, Ferris Bueller's Day Off, Dirty Dancing, The Rocky Horror Picture Show and Marvel's The Avengers, along with TV shows such as Doctor Who, Scooby-Doo and Sesame Street.
