If it is greenlighted, Morgan will make his directorial debut with the film, about the political relationship between Bill Clinton and Blair.
This would be the third time Sheen portrays former British PM Blair. He played him in two Stephen Frears movies penned by Morgan: 2003's "The Deal" and 2006's "The Queen."
Kathleen Kennedy, Morgan and Andy Harries are exec producing "Relationship," which the BBC is in talks to co-produce with HBO.
Ann Wingate and Frank Doelger serve as producers.
