On 1 September 2007 Williams visited the Kurdish Cultural Festival in Gelsenkirchen, Germany, where he spoke of the importance of the maintenance of the Kurdish language.
He played the role of Lamb in the television film Dutch Girls (1985), which starred Colin Firth and Timothy Spall, and appeared in three episodes of Dramarama between 1983 and 1985, playing a different character in each.
In February 2010 Davies' work was mentioned, by Conservative MP David Davies and Plaid Cymru MP Hywel Williams, in a Parliamentary debate concerning heath-care in Wales.
