A serial killer who calls himself "Overkill" has been terrorizing Los Angeles, and the most recent victim was "Red" Bailey, an old friend of Joe Mannix. But as Mannix and the police look into Bailey's killing, they learn that Bailey was investigating the Overkill case on his own -- and may have discovered that at least one of the killings attributed to Overkill was a copycat murder that someone wanted to be blamed on Overkill.

Interesting paring of blacklisted actor Jeff Cory and "friendly witness" Marc Lawrence in Overkill. See more »


During the chase through the Japanese Village, the use of a stunt double for Joe Mannix is evident shortly before Mannix runs across the red arched bridge. See more »


Lt. Art Malcolm: [interrogating Overkill in his office] You're entitled to have an attorney present. You do understand that?
Overkill: I'm... my own attorney.
Paul Sorenson: I don't think he understands. I have an attorney standing by. Good man. I'll call him.
Overkill: [slams his hands over the phone on Art's desk] I DON'T WANT YOUR GOOD MAN! YOU'VE ALREADY DOUBLE-CROSSED ME ONCE!
Paul Sorenson: I'm trying to help you.
Overkill: That why you had those calls traced. I knew what you were doing. The minute I left those phone booths... the police had arrived.
Paul Sorenson: The first words...

An interesting idea but not much more
19 November 2014 | by MartinHaferSee all my reviews

"Overkill" is a neat idea for an episode of a detective show. A serial killer who calls himself 'Overkill' has killed several people and likes to call a TV celebrity and talk about it. This hubris is his undoing, as eventually the police are able to track his phone calls and capture him. But there is a problem--one of his supposed victims may have actually been killed by someone else who deliberately has copied the m.o. of this psychopath. But, this would mean that the killer would need to know details that very few people could provide...making this an inside job.

So why did I give this great idea only a 6? Well, too many times the show resorted to Mannix-style clichés instead of allowing the plot to unfold normally. Once again, Mannix gets bashed over the head and is knocked out, once more Mannix brings the killers to a lonely place for a showdown and the police arrive just in the nick of time and much more that is too familiar. This could have been better.
