New episodes of the 1970s PBS hit Upstairs, Downstairs are coming to Masterpiece in 2011 as part of a co-production deal with BBC World Sales and Distribution, Americas, the partners announced in a press release today. There’ll also be a 21st-century version of Sherlock Holmes, and three Aurelio Zen mysteries about a fictional Italian detective. The original Upstairs, Downstairs won seven Emmys including a best actress for Jean Marsh; she’ll recreate her role of Rose the parlor maid. The three-part series will be set in the same house. The new episodes take place in 1936, advancing the storyline that left off in 1930. Read more in the UK’s Guardian.
