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, and the show was a breakout hit, running until its promoters could no longer reserve a stage in the West End, due to theaters being booked for the upcoming season. Chaplin's comic performance, in particular, 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?
NO.
