Twenty Thousand Streets Under the Sky is a 2005 BBC television serial depicting the intersecting lives of three working-class Londoners in the 1920s.

The series is based on the trilogy 20,000 Streets Under the Sky by British author Patrick Hamilton.

The Los Angeles Times called the series "a dreamy but gritty period drama, superbly acted" and "the kind of television at which the BBC repeatedly excels – rich and fulfilling for its understatement, discreet tales that are well told.

"[2] Variety praised the series, writing that it "brims with a sense of yearning that takes the very old quandary of not being able to control who one loves and puts an evergreen spin on it.

Moreover, the production itself is as meticulous as the storytelling, from the drab palette used in capturing the Depression-era surroundings to the melancholy score.
