Sir Henry at Rawlinson End

Sir Henry at Rawlinson End is a 1980 British film based on the eponymous character created by Vivian Stanshall. It stars Trevor Howard as Sir Henry and Stanshall himself as Henry's brother Hubert. Unusually, the film was released in sepia-toned monochrome. After a long wait, while the film obtained cult status, it was finally released on DVD in 2006. The bonuses include a commentary track with the director, Steve Roberts, as well as Sheila Reid and Jeremy Child, as well as a picture gallery, synopsis, the script of unfilmed scenes, and actor biographies.
