'MJ: The Musical' Producer John Branca's Backstage Visit with Star Myles Frost

When "MJ: The Musical" meets "The Producers" ... you get a little something like this.

John Branca -- one of the guys behind Broadway's biggest spectacle right now -- went backstage Friday night with his wife, Jenna, to meet the show's lead star ... Myles Frost, who plays Michael. They had a cool little photo-op moment together -- flashing smiles and looking sharp.

'MJ' has been playing since earlier this February -- after a lot of delays, due to COVID -- and so far ... it's a smash hit. Not only has it been commercially successful, but it has sat well with critics too ... even snagging a handful of Tonys this year, including for Frost.

He won Best Actor in a Musical -- and 'MJ' has won some technical Tonys too, such as Best Choreography, Best Lighting Design and Best Sound Design. It's about Mike's real-life 1992 Dangerous tour, and the show gives a BTS glimpse at some of his imagined rehearsals.

Of course, it also covers a ton of MJ hits along the way ... with his signature dance numbers to boot. There was controversy around this at first, but most of that seems to have fallen by the wayside, especially this many months into a long and consistent run.
