10 Behind The Scenes Reasons For DCEU Characters' Quirks

10. Mera's Suddenly Changing Accent

When Mera (Amber Heard) appeared in the 2017 Justice League and then Aquaman's solo film the next year, she touted an American accent as you'd probably expect.

And yet, when she subsequently showed up in Zack Snyder's Justice League, she bafflingly rocked a British accent, as left fans utterly mystified. What could possibly be the rationale behind such an incongruous, distracting creative choice?

In actuality, it seems that Mera's British accent was the original choice for the character, and when Joss Whedon took over production of Justice League, he opted to have Amber Heard re-dub the dialogue into an American accent.

Heard then simply kept the American accent for Aquaman, but Snyder was able to revert to his original filmed footage for the Snyder Cut, while also asking Heard to use the British accent again for the newly-shot Knightmare sequence at the very end of the film.

All in all it really just confirms that Zack Snyder's Justice League is a narrative "cul-de-sac," as Snyder himself puts it, especially as Mera will presumably be speaking with an American accent once again in the upcoming Aquaman and the Lost Kingdom.
