Depp filed the defamation complaint against Heard in the United States after losing a separate, high-profile libel case in London in November 2020 that he brought against The Sun for calling him a "wife-beater."
In 2016, Heard sought a restraining order against Depp. Their divorce was finalized in 2017, with Heard receiving a $7 million settlement.
A panel of seven jurors and four alternates is hearing the case between Depp and Heard, who had a starring role in "Aquaman."
