The role of Detective Steve Carella was played by Burt Reynolds in the poorly received 1972 film Fuzz. Jack Weston played Detective Meyer Meyer and Tom Skerritt played Detective Bert Kling.
Robert Lansing originally played Detective Steve Carella in the 1960 film The Pusher. When Lansing began playing the role in the TV series he claimed that the producers told him they were unaware he'd previously played his TV character on the big screen.
Carella (to Meyer from the water): Throw me down the bailing hook. I got a piece of garbage down here.
Curt (to Teddy): Men don't like me but women do.
Kling (after hurriedly passing a woman on his way out of the squad room): Meyer! That was Claire!
Meyer: Not very friendly, was she?
Havilland: Sit down, Miss Taylor, or would you like me to call you by your professional name?
Stripper: You couldn't pronounce it.
Chan (to Carella about Teddy): Very pretty wife. You lucky detective.
Priscilla (to Curt): I know what I look like. I try to be honest.
Carella: Was she pretty?
Dr. Blaney: After three weeks in the water nobody's pretty.
Fans of Daniel Boone might recognize Dal McKennon in a recurring role as an autopsy surgeon. McKennon appears here minus the long beard he wore when playing tavern owner Cincinnatus on the former show. 87th Precinct star Robert Lansing would later appear with McKennon on Daniel Boone in an episode entitled The Tamrack Masscare Affair.
It's revealed at the end of this episode that Steve and Teddy Carella sleep in the same bed. They must have been one of the first TV couples to do so because during that era couples slept in twin beds due to censorship rules.
Robert Culp would later find stardom when he co-starred with Bill Cosby in the NBC comedy drama I Spy.
Victor Sen Yung is best known to TV viewers for his recurring role as cook Hop Sing on Bonanza.
This episode was based on Ed McBain's novel The Con Man.
