Warner Bros. and DC Films had previously announced that Keoghan was playing a character named Officer Stanley Merkel back in August 2020 when they released a teaser for the film at DC FanDome.

In the description of the video it reads, “Barry Keoghan (‘Dunkirk’) as Officer Stanley Merkel.”

Keoghan even shared a photo of himself wearing a Batman crew sweatshirt in April 2021.

Merkel is a relatively obscure character in DC Comics. He was created by Frank Miller and first appeared in Batman: The Dark Knight Returns #1.

He would be introduced into the main Batman continuity in Batman #405 as part of Frank Miller and David Mazzucchelli’s Batman: Year One story arc.

He primarily appears as a patrol cop with his face hidden and a only a silhouette shown.

If Keoghan is playing The Joker, it’s possible he’s posing as Merkel.

The Joker posing as a police officer is not unheard of especially in live-action. Heath Ledger’s Joker posed as a police officer in an attempt to assassinate Gotham’s mayor. However, the attempt was foiled and he shot Jim Gordon in the back instead.

Jerome Valaska also posed as a police officer in Gotham when he took out the GCPD headquarters and kidnapped GCPD Commissioner Sarah Essen.
