James Roday (“Miss Match,” “The Dukes of Hazzard”) as young police consultant
Shawn Spencer who solves crimes with powers of observation so
acute the precinct detectives think he's psychic – at least that’s
what he lets them believe.
Dulé Hill (“The West Wing”) as Shawn's best
friend and reluctant sidekick Gus.
Corbin Bernsen (“Kiss Kiss Bang Bang,” “L.A.
Law”) as Shawn's disapproving father,
Henry Spencer, who ironically was the one who honed his son's
"observation" skills as a child.
