Dick Van Dyke to do 'a little song and dance' in Mary Poppins sequel

Dick Van Dyke will dust off his dancing shoes for Mary Poppins Returns, Disney's sequel to the 1964 movie musical in which he costarred with Julie Andrews.

The 91-year-old entertainer recently confirmed to Entertainment Tonight that he's set to make a cameo in the new film, which will star Emily Blunt in the title role, along with Lin-Manuel Miranda, Meryl Streep, and Colin Firth. Rob Marshall is directing.

"Well, I've got to be a part of it," Van Dyke said, adding that he'll travel to London to shoot in the spring. "I think I'll just have the one scene, and a little song and dance in it."

Van Dyke won't be reprising his main role as Bert, the cockney jack-of-all-trades who accompanied Andrews' magical nanny, but his character will be somewhat familiar: He's playing the son of the elderly banker he portrayed in the original, then wearing copious makeup.

"This time there's no four hours in the makeup chair," Van Dyke said. "I grew into the part. I don't have to wear makeup at all." <iframe frameborder="0" width="533" height="300" scrolling="no" src="http://link.brightcove.com/services/player/bcpid1250536613001/?bctid=5254568797001" class="" allowfullscreen="" resize="0" replace_attributes="1" name=""></iframe>
