OK, the laugh-a-minute Seinfeld reunion on Curb Your Enthusiasm, this probably won’t be. But The Ausiello Files has learned that The Shield executive producer Shawn Ryan has rounded up half a dozen members of his old show’s cast to guest star on his new show, Lie to Me.

Through next Tuesday, hard at work on the season’s 12th episode, “Pied Piper,” will be Shield alumni Benito Martinez, Catherine Dent, Kenny Johnson, David Marciano, Cathy Cahlin Ryan and David Rees Snell. The hour’s plot: Lie to Me‘s regular crimefighters, Lightman (Tim Roth) and Zoe (Jennifer Beals), wonder whether (oopsie!) they sent the wrong child murderer to prison nearly two decades earlier.

So who’s who?

Marciano plays the Death Row killer; Ryan, his ex; Snell, his snitch of a brother; Martinez and Dent, the uncle and aunt of the ill-fated little boy; and Johnson… let’s just say he becomes a person of interest in the case.

So what do you think? Incredibly cool stunt-casting or the kind of cheap gimmick Lie to Me honestly doesn’t need? (After all, it did just receive its back-nine pickup order.) Make your voice heard below. You’ll need to speak up, though. Internet is spotty where Mike is.
