Wil Cwac Cwac is a Welsh-language cartoon based on a series of children's books written in the 1920s by Jennie Thomas and J. O. Williams. The cartoon series ran from 1982 to 1987 on ITV. Both book and cartoon series take place in rural Wales. The Welsh-language series was produced by Siriol Animation for S4C. An English-language version of the show was produced for the wider English-speaking market. In both versions, all narration and characters were voiced by Myfanwy Talog. An American English dub was also made, with Liza Ross narrating. This version aired in the United States on the Disney Channel. The English version of the series has not been released on DVD, although the Welsh version can be purchased from Sain Wales. Previously, Family Home Entertainment and Abbey Home Media released Wil Cwac Cwac on VHS; these videos have gone of out print since the end of the 1990s.
