In Ronald Neame's film of Joyce Cary's classic novel, Alec Guinness transforms himself into one of cinema's most indelible comic figures: the lovably scruffy painter Gulley Jimson. As the ill-behaved Jimson searches for a perfect canvas, he determines to let nothing come between himself and the realization of his exalted vision. A perceptive examination of the struggle of artistic creation. The Horse's Mouth is also Neame's comic masterpiece.
