St. Martin’s Lane, also known as Sidewalks of London, stars Charles Laughton as a busker who teams up with a pretty, young pickpocket (Vivien Leigh). Rex Harrison plays a theater patron who is impressed by the pickpocket’s dancing and brings her into their theatrical troupe, launching her career.
In Leonard Maltin’s Classic Movie Guide, he calls out 26 memorable performances from A to Z, and the V is Vivien Leigh’s work in Sidewalks of London. It was her last movie before she starred in Gone With the Wind, and it’s worthy of inclusion in the Internet Archive Top 100.
