New footage confirms Amber Heard is in 'Aquaman 2' despite rumors she was cut out of the movie

• A new trailer confirms Amber Heard is in "Aquaman and the Lost Kingdom."
• During CinemaCon on Tuesday, which Insider attended, a trailer of the movie was shown.
• Heard's Mera character appeared briefly in two shots.

Amber Heard is in the anticipated sequel to "Aquaman."  

The first trailer of "Aquaman and the Lost Kingdom" was shown at CinemaCon, the annual movie theater convention, on Tuesday during a presentation by Warner Bros, attended by Insider.

Heard, who played Mera, the love interest of Aquaman (Jason Momoa) in the hit 2018 original movie, is featured in two brief shots during the trailer in which she's doing battle underwater. She has no dialogue in the trailer. 

In June of last year, a now-deleted post on Just Jared reported that Heard was being "cut out" of the sequel.

"The rumor mill continues as it has from day one — inaccurate, insensitive, and slightly insane," a spokesperson for Heard told Insider in response to the post.

Heard's Mera character was first introduced in the 2017 film "Justice League" before becoming a protagonist in 2018's "Aquaman" alongside Momoa.

During her defamation trial with her former husband, Johnny Depp, Heard said her role was heavily reduced in "Aquaman and the Lost Kingdom."

"I fought really hard to stay in the movie — they didn't want to include me in the film," Heard said on the stand, adding that she performed "a very pared-down version" of the role that took away action scenes between herself and another character. 

If the trailer is any indication, Heard's Mera is not the main supporting character she was in the first movie. Instead of Aquaman and Mera teaming up for most of the movie, in the sequel, it's Aquaman and his half-brother Orm Marius, played by Patrick Wilson. 

"Aquaman and the Lost Kingdom" opens in theaters on December 20.
