The Batman finds its music composer in Michael Giacchino

Composer Michael Giacchino is officially on board to work in The Batman. Filmmaker Matt Reeves surprised the crowd Friday at an event at London's Royal Albert Hall, where Giacchino and fellow composer David Arnold were engaging in some friendly competition by comparing works they've done.

When Reeves took the stage, he got down on one knee in a mock proposal, asking Giacchinoto to join his project.

Reeves and Giacchino have worked together numerous times, beginning with Cloverfield, the 2008 found footage monster movie that launched Reeves' career as a director and for which Giacchino composed the end credits song. 

Giacchino has also worked with Reeves on Let Me In (2010), Dawn of the Planet of the Apes (2014) and War for the Planet of the Apes (2017).  

The composer is no stranger to the superhero movie business, having composed scores for Spider-Man: Homecoming (2017), Spider-Man: Far From Home (2019), The Incredibles (2004), and The Incredibles 2 (2018). He also has Marvel's Doctor Strange in the Multiverse of Madness coming up.

Warner Bros is set to release The Batman on June 25, 2021.
