LEGO Batman Movie: 75 Easter Eggs & References You Need To See

48. The Batcave Museum

When Batman returns to the Bat-Cave, he sends The Joker's mega-bomb to the Bat-Museum, to join the other memenoes he has collected over the years. It's only on screen for a moment, but you can definitely see the giant coin that's always been part of his collection, and the iconic T-Rex is also there.

47. 'Puter

Hilariously, Batman's personal AI, which he calls 'Puter and which helps him drive the Batmobile and control the Bat-Cave, is credited as being voiced by Apple's Siri, and is indeed voiced by Siri's human voice Susan Bennett.

46. Bludhaven

Barbara Gordon's introduction at her big announcement event that is tagged on to her father's retirement party sees her billed as having worked in (and cleaned up) Bludhaven.

Most comic book fans will be aware that the Gotham neighbour city is the home of Nightwing, but Batgirl (otherwise known as Barbara Gordon) also temporarily set up her own Batcave there. So it's a nod to her in-comics mythology.
