Actor James Franco is now reportedly involved in the ongoing legal battle between exes Johnny Depp and Amber Heard.

Axar.az reports citing Fox News.

According to The Blast, which was first to report the news, Depp's legal team is sending a subpoena to Franco after surveillance video footage surfaced, allegedly showing the 41-year-old film and TV star in an elevator with Heard one day after the former acting couple's May 2016 fight.

In a statement to The Blast on Tuesday, Depp's attorney, Adam Waldman, said, "We are interested in James Franco and Elon Musk as fact witnesses because we have evidence they are men who saw Amber Heard's face in the days and nights between when she claimed Mr. Depp smashed her in the face on May 21 and when she went to court with painted on 'bruises' to obtain a temporary restraining order on May 27."

In the video, obtained by the outlet, Heard, 33, is seen riding in an elevator -- for the downtown Los Angeles apartment she once reportedly shared with Depp, 56 -- by herself before she gets out and then reappears with Franco.

According to The Blast, the civil subpoena is a part of Depp's $50 million defamation lawsuit against Heard, which he filed earlier this year after the actress wrote a Washington Post op-ed about domestic abuse. Depp’s complaint says that although Heard did not use Depp’s name in the Post article, it was clear she was referring to him.
