More than a decade ago, a report surfaced that Paramount intended to develop a Teddy Roosevelt biopic starring Leonardo DiCaprio and directed by Martin Scorsese. The year was 2006, and, at that point, Scorsese and DiCaprio had collaborated a mere three times over the previous five years: in 2002’s Gangs of New York, 2004’s The Aviator, and 2006’s The Departed. (DiCaprio earned his first Best Actor Oscar nomination for his role as Howard Hughes in The Aviator.)

They were certainly not novice collaborators—DiCaprio was well on his was to becoming the Samuel L. Jackson to Scorsese’s Tarantino—but they had yet to make films like Shutter Island or The Wolf of Wall Street; they had yet to sign on to develop not one but two true-crime dramas for the screen; and they probably had yet to merit their own joint Wikipedia page.
