Feet First is a 1930 American Pre-Code comedy film starring Harold Lloyd, a very popular daredevil comedian during the 1920s and early 1930s. It was Lloyd's second and most popular sound (' talkie') feature. It is also one of his 'thrill' comedies, involving him climbing up a tall building. Harold Lloyd was one of very few silent film actors who successfully adapted to sound.
