Jon Landau, an Oscar-winning producer of "Titanic," "Avatar" and its sequel "The Way of Water," has died. He was 63 years old. 

Landau's death was confirmed by Disney Entertainment co-chairman Alan Bergman, who called him a "visionary."

"Jon was a visionary whose extraordinary talent and passion brought some of the most unforgettable stories to life on the big screen," Bergman said of Landau. His remarkable contributions to the film industry have left an indelible mark, and he will be profoundly missed. He was an iconic and successful producer yet an even better person and a true force of nature who inspired all around him."

Landau started his career in Hollywood in the 1980s, first working as a production manager, then as a co-producer on classics like 1989's "Honey I Shrunk the Kids" and 1990's "Dick Tracy."

He eventually became a close collaborator with "Titanic" and "Avatar" director James Cameron, joining his Lightstorm Entertainment production company as an executive.

"I can’t act and I can’t compose and I can’t do visual effects, so I guess that’s why I’m producing," Landau joked alongside Cameron during their acceptance speech when "Titanic" won best picture in 1998. 

During "The Way of Water"'s post production in 2022, Landau told The Associated Press that despite the ways in which people consume movies changing, the reason we watch is the same.

"One of the things that has not changed is: Why do people turn to entertainment today? Just like they did when the first ‘Avatar’ was released, they do it to escape, to escape the world in which we live," he said.

A dead body was found wrapped in a sleeping bag on top of a dolly along a New York City sidewalk Friday, according to police. 

The shocking daylight discovery was made after police responded to a 911 call about a suspicious package in Manhattan’s East Side neighborhood of Kips Bay just before 5 p.m., the NYPD says. EMS responded to the location and pronounced the person dead. 

Video from the scene shows the dark-colored sleeping bag with the body inside atop the dolly surrounded by black trash bags which were waiting for collection. The dolly was tied to a scaffolding railing by a red strap.

Ted Oehmke, who shot video of the grim scene from inside a friend's building, tells Fox News Digital that on Thursday night he noticed a BMW SUV parked next to where the body was found with its hatch open. The vehicle was not there on Friday afternoon. 

He says he is baffled by the discovery. 

"That's a lot of trouble to go through… and then and then to do all that and then just drop it on the sidewalk," he said. "If they don't get caught I’ll call them geniuses because, with the cameras and everything, I don't know how you would expect to get away with [that]."

The cause of death is unclear and police have not publicly identified the body. The Medical Examiner will ultimately determine the cause of death.

Oehmke says he saw police open the top of the bag, and it appeared to show a white or Hispanic man in his 60s. 

The body was outside a now-shuttered alterations store called "Apel’s Alterations." The owner died a few years ago, Oehmke says. 

Oehmke says he has lived in the neighborhood for 30 years, and it is known for people sleeping rough.

"For some reason, I'm just not really surprised. I don't know, I guess it doesn't happen that often, but I see people sleeping around here in all kinds of ways too," he said. "Sleeping in the garbage or curled up and stuff, and it looks like people are dead. I've seen people that I thought were dead before, but they're actually alive."

"There’s a lot of activity around here. The Bellevue ‘psych’ hospital is down the block and the largest men's shelter in the city is here," he added.

No arrests have been made, and the investigation is ongoing, police say.
