Alias: Walter Wright Williams, Walter Williams Wright, Robert Buchanan
Presumably either American or British, Walter Williams was a character actor who spent his entire career in Italy, appearing in several Italian films as well as international productions shot in Italy. His earliest known roles date back to the early 1960s, at which point he went under the name Robert Buchanan, but as of the mid 60s, he went by Walter Williams. His most prominent roles were in La decima vittima (1965) and Dottor Jekyll e gentile signora (1979).
On the film Fräulein Doktor (1969) he is credited as a dialogue coach, and it's quite possible he also took on that job uncredited in other films.
