Quentin Tarantino received an extremely rare deal for his upcoming film "Once Upon a Time ... in Hollywood." 

While many directors fight to get final cut, Tarantino got something even more precious: copyright control.

According to The Hollywood Reporter, Sony agreed to a deal that gives Tarantino full ownership of the underlying copyright to the movie after 30 years (with some sources saying it's a much shorter time table).

Owning the copyright allows a director to share in each part of the revenue stream and eventually sell their stake to a library.

Tarantino joins an exclusive club of directors who have had ownership stakes in their films, including George Lucas, Mel Gibson and Richard Linklater.

To get a copyright deal, those directors had to pony up either their money or time. Lucas took a smaller fee on the original "Star Wars" movie to keep ownership of the merchandising, licensing, and sequels. Gibson was able to get the copyright deal because he self-financed "The Passion of the Christ." Linklater staked 12 years of his life making "Boyhood."

Tarantino didn't have to make similar sacrifices, but Sony was still willing to make the deal. That means if he does somehow end up making a "Bounty Law" TV series (the show seen in "Once Upon a Time in Hollywood"), Tarantino will own it, not Sony.
