"Titanic" director James Cameron is speaking out after the search for the missing OceanGate Titan submersible came to a devastating end Thursday.

Cameron, 68, found the tragic story of the sub eerily similar to what happened to the doomed ship Titanic in 1912.

"Well, I've been down there many times," Cameron told ABC News on Thursday. "I've made 33 dives and I've actually calculated that I've spent more time on the ship than the captain did back in the day."

Cameron noted that he is a submersible designer himself and even created a sub that was capable of traveling to the deepest parts of the ocean, which is three times deeper than the location of the Titanic, according to the director.

He dove to the Mariana Trench in a 24-foot submersible called the Deepsea Challenger in March 2012.

Cameron noted that "many people in the community were very concerned about this sub." He said "a number of the top players" in the community "even wrote letters to the company saying that what they were doing was too experimental to carry passengers."

"I’m struck by the similarity of the Titanic disaster itself, where the captain was repeatedly warned about ice ahead of his ship and yet he steamed at full speed into an ice field on a moonless night and many people died as a result," Cameron told the outlet. 

"And for a very similar tragedy, where warnings went unheeded, to take place at the same exact site, with all the diving that’s going on all around the world, I think is just astonishing. It’s really quite surreal," he concluded.

The U.S. Coast Guard confirmed Thursday that a debris field is the missing Titanic tourist submersible that was carrying five passengers. All five on board are presumed dead.

"These men were true explorers who shared a distinct spirit of adventure, and a deep passion for exploring and protecting the world’s oceans," OceanGate said in a statement. "Our hearts are with these five souls and every member of their families during this tragic time."

Cameron released the National Geographic documentary, "Titanic: 25 Years Later," in February. The documentary addressed the controversial theory that Leonardo DiCaprio's character, Jack, could have survived by climbing onto Rose's (Kate Winslet) door in the middle of the freezing waters.
