Perry Mason - Partitura mortale

When universally disliked theater director Dwight Schultz is killed, Jim Metzler faces a charge of murder, despite Raymond Burr stating he saw Metzler at the time of the murder. Perry Mason is cross, so he takes the defense case, so you know going in that there are half a dozen good suspects and the killer will confess on the witness chair.

William Katt is gone from the TV movie series as Paul Drake Jr., but his place taken by young attorney William R. Moses and his rich girlfriend, Amanda Cody.

Because the murder centers around a Broadway-bound musical, there are plenty of musical-comedy players, including Debby Reynolds as the diva of the company and Jerry Ohrbach as the producer. It's a typically fine entry in the series of movies starring Burr as Erle Stanley Gardner's lawyer.
