In 2002, "lost" episodes of Jerry the Troublesome Tyke were discovered and brought back to life.
Jerry the Troublesome Tyke was a series of shorts created by Sid Griffiths during the silent film era. Forty-two shorts, about 4 minutes long, were made between 1925 & 1927 and were shown at the big screen at Cardiff's Capital Cinema in Wales. The charismatic and cheeky dog lives on paper on Griffiths drawing board, and is often visited by Griffiths. This was the first animated series to be made in Wales, and was also the longest running British animated series during that time.
