So, there's some fun news today. As many people know, Shawn Ryan (creator of The Shield) is now the showrunner for Fox's Lie to Me. Well.......in episode 12 of this season, Ryan is bringing back 6 of his Shield stars in guest roles.
They are Benito Martinez (Aceveda), Catherine Dent (Danni), David Marciano (Billings), Cathy Cahlin Ryan (Corrinne Mackey), David Rees Snell (Ronnie), and Kenny Johnson (Lem).
According to Ryan's Twitter page, both Walton Goggins (Shane) and Jay Karnes (Dutch) were too busy to shoot spots. Maybe in future episodes? One can hope.
