Barratt's scene in 2018's "Mary Poppins Returns" may have been brief, but it kicked off the film's first musical number, and saw the young actor make his feature film debut alongside some serious star power. And that's saying a lot, given that the actor had already starred alongside the likes of Jeremy Piven and Jodie Komer by the time 2018 rolled around.

In director Rob Marshall's ambitious, Oscar-nominated follow-up to Robert Stevenson's 1964 classic ("Mary Poppins"), "Hamilton" writer and star Lin-Manuel Miranda plays Jack — a former apprentice to Dick Van Dyke's beloved Bert who serves as a kind of reincarnation of the latter in Marshall's film. Although Miranda was already a Grammy, Tony, and Emmy award-winning artist, actor, and composer by the time he tackled the role of Jack in 2018, the film marked his biggest motion picture debut to date, and his performance would garner him a litany of further awards and nominations (via IMDb). 

Though Barratt and Miranda don't share a whole of screentime in the film, Barratt does add to the inspiring message behind lamplighter and eternal optimist Jack's opening number, and the former's next major project would involve another contemporary singer and songwriter (albeit in a kind of roundabout way).
