UCP has brought together a stellar cast for a series which presents a modern take on the Watergate scandal.

This prospective series, titled `Gaslit,` will star Julia Roberts, Sean Penn, Armie Hammer and Joel Edgerton, and has `Mr. Robot` creator Sam Esmail on board as an executive producer. UCP plans to shop the project around to premium and streaming platforms. Given the talent attached, it will likely cause quite the bidding war.

Based on the Slate podcast `Slow Burn,` the show focuses on the untold stories and forgotten characters of Watergate, from Nixon's bumbling, opportunistic subordinates, to the deranged zealots aiding and abetting their crimes, to the tragic whistleblowers who would eventually bring the whole rotten enterprise crashing down.

Roberts will star as Martha Mitchell, a big personality with an even bigger mouth, who is a celebrity Arkansan socialite and wife to Nixon's loyal Attorney General, John Mitchell, played by Penn. Despite her party affiliation, she's the first person to publicly sound the alarm on Nixon's involvement in Watergate, causing both the Presidency and her personal life to unravel. Penn's Mitchell is described as temperamental, foulmouthed and ruthless - yet hopelessly in love with his famously outspoken wife. He'll be forced to choose between Martha and the President.
