Mysteries of Laura is getting Lost.
EW has learned exclusively that Lost alums Harold Perrineau and Greg Grunberg have landed guest-starring roles on an upcoming episode of Debra Messing’s NBC series.
When a tragic accident involving a prominent sports doctor turns into a murder investigation, Laura (Messing) and team work together to track down the killer. Perrineau, who played constantly-screaming-Waaaaaaaaaaalt survivor Michael Dawson, will portray Charles Baptise, a tiger dad with Olympic-sized anger issues whose son is a former Olympic gymnast. Heroes alum Grunberg, who portrayed the pilot of the ill-fated Oceanic flight 815, will play Kurt Berhenson, an ex-husband fighting over custody of his son and a loyal member of a men’s rights group.
