The Heavyside Lair is Basically Cathalla

It's been around a decade since I became enamoured with Cats. I watched that officially recorded video of the stage show from the 90s and bought the soundtrack, which I still listen to. When I was 20, I did my final night of trick-or-treating as Rum Tum Tugger, which was followed by a night on the town that saw me walk into a bar for the lavatory and win their costume contest withouth actually entering it.

Anyway, I was primed for the movie version, and it triumphed. It really filled out the source material in wildly fantastical ways, and it clearly showed the wonders achievable by adapting stage musicals. I've long thought that more productions could be given that treatment. "Hamilton" is an obvious choice for sheer popularity, and I'd be intrigued at the prospect of a cinematic "Wicked". 

Basically, "moar plz."

Bonus Question!

Best cinematic musical?

"Moulin Rouge!"
