Lin-Manuel Miranda is stacking up some impressive roles since stepping off the Hamilton stage: first as Mary Poppins’ right-hand man in Mary Poppins Returns, and now balloonist Lee Scoresby in His Dark Materials.

Deadline reports that the Hamilton creator is in talks to join the cast of the upcoming adaptation of Philip Pullman‘s beloved book trilogy, which EW has now confirmed.

Played by Sam Reilly in the 2007 film The Golden Compass, the character Lee Scoresby is a Texan aeronaut, who helps protagonist Lyra Belacqua on her mission to find some missing children.

Not many details have been released since the landmark adaptation was announced more than two years ago, and news of Lin-Manuel’s involvement is one of just a few tidbits leaked yesterday (March 8).

The eight-part series will reportedly be directed by Tom Hooper, who won the Oscar for Best Director for The King’s Speech, while twelve-year-old Dafne Keen, who got our attention with her breakout role in Logan, is close to being cast as the books’ protagonist Lyra.

It will cover all three books of the trilogy — The Golden Compass, The Subtle Knife, and The Amber Spyglass — and will be written by Harry Potter and the Cursed Child writer Jack Thorne.

Philip Pullman fans will be hoping for a more faithful adaptation, after the 2007 film starring Daniel Craig and Nicole Kidman failed to live up to expectations.

Who’ll play their respective roles of Lord Asriel and Mrs. Coulter is yet to be announced, but fingers crossed it’ll be two equally impressive stars. Production is due to start “soon,” so presumably we won’t have long to wait for further casting announcements.

And with Lin-Manuel taking up his seat aboard what might just be literature’s most famous hot-air balloon, we’re expecting very good things from this adaptation.

Are you excited too?
