text_A: In the years Chaplin was touring with the Eight Lancashire Lads, his mother ensured that he still attended school but, by age 13, he had abandoned education. He supported himself with a range of jobs, while nursing his ambition to become an actor. At 14, shortly after his mother's relapse, he registered with a theatrical agency in London's West End. The manager sensed potential in Chaplin, who was promptly given his first role as a newsboy in Harry Arthur Saintsbury's "Jim, a Romance of Cockayne". It opened in July 1903, but the show was unsuccessful and closed after two weeks. Chaplin's comic performance, however, was singled out for praise in many of the reviews.
text_B: If a faithful biography was to be written about Chaplain's early career, would "Jim, a Romance of Cockayne" be more likely to be described as a disappointing background against which a future star nevertheless managed to shine, rather than a confluence of good writing, good directing, and a good cast that helped a promising young actor to discover his potential?
YES.
