Along with the news of the first Captain Marvel trailer reportedly set to premiere next Tuesday, it appears we’ve also got an update on a new, much long-awaited, look at Mary Poppins Returns.

The same Good Morning America callsheet which made its way to the Marvel Studios subreddit earlier this morning, later verified by MCU Cosmic, includes a listing for the brand new trailer launch for Rob Marshall’s film in the penultimate segment of the ABC show (around 5am PT/8am ET/1pm UK) this coming Monday, September 17. The new look is set to be introduced by stars Emily Blunt and Lin-Manuel Miranda, and has been months in the making after the first teaser trailer premiered at the Oscars back in March.

UPDATE: The just-shared press release on Disney’s official website makes no mention of the Poppins cast appearance, with the Captain Marvel Brie Larson link up the following day confirmed. A change of plan for the Poppins debut is very much possible at this point.

As with the Captain Marvel report, due to the nature of how the call sheet leaked, there is every chance that these plans may change. But in the meantime, be sure to have the time and date in your diaries and we will update with official information on the trailer as soon as Disney or related parties announce it.

In 1930s depression-era London, Michael and Jane Banks are now grown up, with Michael, his three children and their housekeeper, Ellen, living on Cherry Tree Lane. After Michael suffers a personal loss, the enigmatic nanny Mary Poppins re-enters the lives of the Banks family, and, along with the optimistic street lamplighter Jack, uses her unique magical skills to help the family rediscover the joy and wonder missing in their lives. Mary Poppins also introduces the children to a new assortment of colorful and whimsical characters, including her eccentric cousin, Topsy.

Starring Emily Blunt, Lin-Manuel Miranda, Ben Whishaw, Emily Mortimer, Julie Walters, Colin Firth and Meryl Streep, the film is released December 19 in the U.S. followed by December 21 in the UK.
