never sought on-screen credit on the series because during his previous tenure at the Canadian Broadcasting Corporation, such credits were not given, and he never thought to get one for The Avengers. The production team changed during the series' long run, particularly between the third and fourth series, but the influence of Brian Clemens was felt throughout. He wrote the second episode and became the series' most prolific scriptwriter. Succeeding producers Leonard White and John Bryce, Julian Wintle became the producer of the 4th series with Brian Clemens credited as associate producer and Albert Fennell credited as "In charge of production". For series 5, made by A.B.C. Television Films (which was created during the run-up to ABC Weekend TV and Associated-Rediffusion forming Thames TV) Clemens and Fennell became co-producers, with Wintle as executive producer. For series 6, after its initial producer John Bryce left, Clemens and Fennell returned as co-producers; early episodes also credit Julian Wintle as consultant to the series and Philip Levene as story consultant. Ray Austin became the fight arranger for series 4 and 5, introducing kung fu to the series. Ray Austin had been training with Chee Soo and they worked techniques from Feng Shou Kung fu and T'ai Chi into the fight scenes and credit sequences. Ray Austin, Diana Rigg and Chee Soo were later awarded a Guinness world record as the first people to show kung fu on television. Later he became a prolific television director. Joe Dunne took over for series 6. Episodes Six series of The Avengers were made between 1961 and 1969. There was an enforced break in filming and transmission towards the end of series five due to financial problems. Television researcher Andrew Pixley and authors Paul Cornell, Martin Day and Keith Topping in their book The Avengers Dossier: The Unauthorised and Unofficial Guide consider the last eight episodes produced after the break as constituting a short series six, and therefore count seven series in total. Within the internal production of The Avengers the last eight episodes were considered to be a continuation of series five. Reception In Canada and the United States Although telerecordings of the second and third series were seen in Canada as early as 1963, the first two series of The Avengers were not broadcast on television in the United States. The American ABC purchased the rights to broadcast seasons 4 and 5 in the United
