HBO and Martin Scorsese's in-kind contribution to Hillary Clinton's 2016 presidential campaign has hit a snag.

The iconic director’s documentary on the 42nd president is on hold thanks to a creative struggle between the project’s key players, according to The New York Times.

The film, backed by HBO, could have been released in time to bolster Hillary Clinton’s presidential aspirations. Now, it appears to be years away … at best.

Though parts of the film were shot over the last two years as Mr. Clinton made a philanthropic visit to Africa and elsewhere, the project is now indefinitely shelved, partly because Mr. Clinton insisted on more control over the interview questions and final version than Mr. Scorsese was willing to give, those people said.

Would the project be favorable to the ex-president? It’s hard to imagine anything other than a fawning portrait given the players involved. One of the documentary’s potential producers is Steve Bing, described by the New York Times as a “Clinton friend and donor.” HBO routinely serves up pro-liberal content, from “Real Time with Bill Maher” to “Last Week Tonight” and the Sarah Palin film “Game Change.”

Scorsese himself described Bill Clinton as a “transcendent figure” after the project’s announcement.

“A towering figure who remains a major voice in world issues, President Clinton continues to shape the political dialogue both here and around the world,” Scorsese said in statement. “Through intimate conversations, I hope to provide greater insight into this transcendent figure.”

The “Goodfellas” director originally agreed to have the Clinton camp involved in the project directly, but apparently said camp’s directives became too much for Scorsese to swallow.

A more illuminating documentary, and one we’ll likely never see, would focus on the behind-the-scenes wrangling behind the project.
