“Confess, Fletch” (** out of four) was an unnecessary third entry/reboot/whatever of the title character (Jon Hamm) finding himself the prime suspect in a series of murders and trying to prove his innocence while searching for the lost art collection of his former wife. Scattershot chuckles throughout and Hamm tries but a little of this does not go a long way. Chevy Chase is nowhere to be found here but Kyle Maclachlan, Marcia Gay Harden, and Robert Picardo help give film a lively supporting cast.
