Yes--though in the titles the film calls itself a sequel to The Invisible Man by H.G. Wells, i.e. the 1897 book the 1933 Invisible Man was adapted from. Pedants, take note.
Inspector Sampson (Cecil Kellaway) blows his cigar smoke around Dr. Griffin's laboratory just in case Griffin is hiding the Invisible Man there: the Invisible Man becomes visible when surrounded by smoke.
