Amber Heard's role in Aquaman came up as part of a completely different lawsuit Depp filed against his former attorney. That lawsuit was recently settled but one unexpected note involved the allegation that Depp personally asked former Warner Bros. chairman Kevin Tsujihara to remove Heard from her role as Mera in DC's Aquaman, and also block her from getting other WB projects. Since that lawsuit was settled, no one had to testify and no evidence came out.
