This series was produced in two batches: seven episodes (mostly without Patrick Newell as "Mother", and none with Rhonda Parker as "Rhonda") were added to the last eight Diana Rigg episodes for broadcast in the US in the spring of 1968: this made up the third series on ABC in America. On the original American broadcasts, these episodes featured the original 'Shooting Gallery' opening/closing titles featuring Tara in a tight-fitting tan outfit with a short skirt, and gunshots as Steed and Tara are shot at by an unseen gunman, which was filmed by Harry Booth. The seven episodes that aired in the US in the spring of 1968 aired in the following order: "The Forget-Me-Knot" on 20 March, "Invasion of the Earthmen" on 27 March, "The Curious Case of the Countless Clues" on 3 April, "Split!" on 10 April, "Get-A-Way" on 24 April, "Have Guns — will Haggle" on 1 May, and "Look- (Stop Me If You've Heard This One) But There Were These Two Fellers..." on 8 May.
