It really is worth reminding yourself every once and a while how unexpected the Lego Movie was.

Pretty much everyone rolled their eyes at the idea of a film about Lego - fun and all as it is - being anything remotely worth seeing or talking about. Yet, Phil Lord and Chris Miller's take on the popular kids' toy worked on so many levels that it's almost hard to think how they could possibly top it.

Two words - space musical.

That's according to Lego Movie Sequel director Chris McKay in a recent podcast interview for Shanilan On Batman. According to McKay, Lego Movie 2 will be a "big musical and space action movie," which frankly sounds amazing. "They need a lot of the writing, a lot of development, not only with script development, but development with songwriters. So it was very ambitious to get that movie out."

The Lego Movie didn't have many musical moments, however The Lonely Island feat. Teagan & Sara did create the infectiously catchy and subversively smart Everything Is Awesome, so it's clear there's form in the area. As for which songwriters and musicians are involved in Lego Movie Sequel remains to be seen, however Mariah Carey played the mayor in Lego Batman Movie - so she could be a possible shout.

The Lego Movie Sequel is scheduled for a 2019 release date, so there's plenty of time between now and then to write a killer soundtrack.
