Charlie Chaplin's first full-length feature blends his Tramp character's established slapstick with unprecedented emotional depth, following the Tramp as he discovers and raises an abandoned infant, forming a deeply loving bond with the boy (Jackie Coogan) over five years, only for authorities to threaten to separate them when the child's birth mother, now a wealthy singer, reenters the picture. Coogan, just six years old during filming, delivers one of silent cinema's most affecting child performances, matching Chaplin's own physical comedy with genuine pathos. Chaplin drew directly on his own impoverished childhood to infuse the film's comedy with real social and emotional weight, establishing the template for "comedy with heart" he'd refine throughout his career. A massive success on release, it remains a foundational text for blending slapstick with genuine dramatic sentiment.
