It is important to notice, however, that the Shakespeare bust does not hide a button to open a door to the Batcave in any of the mentioned versions except for the Adam West one. In Arkham Knight, players can find the Shakespeare bust inside the Wayne Manor close to a portrait of Tim Drake and Barbara Gordon.

In Gotham, a show that would often combine the tones of different Batman iterations into one distinct look, Bruce Wayne's home also spots a Shakespeare bust as part of the living room. In Nolan’s The Dark Knight Rises, when John Blake confronts Bruce Wayne about Batman’s true identity, it is possible to notice the Shakespeare bust on a bookcase close to Blake.

Matt Reeves’ The Batman was not the first modern Batman iteration to reference the Shakespeare bust from the 1966 show.
