According to EW, the documentary, titled Titanic: 20th Anniversary, will premiere on the cable channel in December.
Titanic writer-director James Cameron is partnering with NatGeo for a new documentary to celebrate the 20th anniversary of the worldwide blockbuster.
In addition, Titanic: 20th Anniversary will follow Cameron and other experts on the doomed ocean liner on a trip to the Ronald Reagan Presidential Library in Simi Valley, California.
If DiCaprio chooses not to participate in Cameron’s Titanic anniversary documentary, the actor’s influence will still be all over NatGeo in another project.
