The special, JFK Jr & Carolyn Bessette: A Camelot Wedding, which was announced last year, was recently acquired by UK indie television content distributor Cineflix from US production company Critical Content, reports RealScreen.

The 120 minute-documentary begins with never-before-seen footage of the wedding on Cumberland Island, with scenes of the Kennedy and Bessette cutting their cake, sharing their first dance, and kissing.

Friends and family, as well as celebrity wedding guests, offer anecdotes and commentary on the lives of the famous couple who died in a plane crash in 1999.

“On an island off of Georgia we came together on this 18th century plantation. In this dirty, dilapidated, shuttered church next to a pig sty,” says a friend of the famous couple in a preview of the special.

“No air conditioning, very little power on the island. It was the best place for them to host a secret ceremony.”

He adds: “Nobody would have expected that three years later we'd be at another church for another reason.”
