The upcoming Showtime limited series chronicling the rise and fall of the late former Fox News chief Roger Ailes, "The Loudest Voice," finally has a release date, and a juicy new teaser trailer to go with it.

"The Loudest Voice" stars Oscar winner Russell Crowe as Ailes, in an astounding physical transformation that leaves the actor almost entirely unrecognizable. It's reminiscent of Christian Bale's spot-on portrayal of Dick Cheney in "Vice," and as the Showtime series intends to argue, both men are equally intimidating -- and equally powerful.

Based on Gabriel Sherman's bestselling book, "The Loudest Voice in the Room," the series aims to examine "the collision between the media and politics," according to Showtime president and CEO David Nevins. Ailes had been considered one of the most powerful political figures in the country before he was forced out of Fox News by a rash of sexual harassment allegations -- including a lawsuit brought by one of the cable network's star anchors, Gretchen Carlson -- in 2016. He died in 2017.

"The Loudest Voice" also stars Naomi Watts as Carlson; Sienna Miller as Ailes's wife, Elizabeth; Seth MacFarlane as former Fox News PR chief Brian Lewis; Simon McBurney as Rupert Murdoch; Annabelle Wallis as former Fox News booker Laurie Luhn; Aleksa Palladino as Ailes' assistant, Judy Laterza; Josh Charles as Gretchen Carlson's husband, Casey Close; and Josh Stamberg as former Fox executive Bill Shine.

The seven-part series will debut on Showtime on June 30.
