Dick Van Dyke as Bert, a cockney jack - of - all - trades and Mary Poppins 's closest friend, who is completely accustomed to her magic. Their playful interactions imply that they have known each other for a long time and that this kind of story has repeated itself many times. Bert has at least four jobs throughout the film: a one - man band, a pavement chalk artist, a chimney sweep, and a kite seller. Dick Van Dyke also portrays Mr. Dawes Sr., the old director of the bank where Mr. Banks works. During the film 's end titles, "Navckid Keyd '', an anagram of Dick Van Dyke, is first credited as playing the role before the letters unscramble to reveal Van Dyke 's name.
