The Supercalifragilisticexpialidocious 'Mary Poppins Returns' Premiere

Blunt and Corden go back "Into the Woods," before Kermit stops by to school the host on "Rainbow Connection."

This video is exhausting.

On Tuesday night, James Corden was joined by "Mary Poppins Returns" stars Emily Blunt and Lin-Manuel Miranda to perform snippets from 22 movie musicals "as fast as we can, in one take." And man, did they deliver.

Standing in front of a green screen, the host asked if his guests were ready. "Born ready," said Lin-Manuel, before Blunt bluntly added, "Not at all."

As they roared through costume and backdrop changes, the trio then tackled famous numbers from "Cabaret," "Chicago," "La La Land," "Beauty and the Beast," "Guys and Dolls," "Evita," "Singin' In the Rain," "Hairspray," "Dreamgirls," "Annie," "Fiddler on the Roof," "Little Shop of Horrors," "Les Miserables," "Moulin Rouge," "Once," "Fame" and "Gentlemen Prefer Blondes."

A few notable moments: Kermit the Frog stopping by to do "Tadpole Karaoke" with Corden to "Rainbow Connection," Miranda dressing up as Toto, and Blunt reuniting with her "Into the Woods" costar to recreate a scene from the movie.

The three brought it home by rocking out to "Dancing Queen" from "Mamma Mia" -- and it's clear Lin was feeling himself with that feather boa!

Watch the incredible production above, before seeing "Mary Poppins Returns" in theaters now.
