In a 2022 interview with Metro, the actor reflected that he didn't know how big of a hit "Titanic" would become while shooting the film, which stood as the highest-grossing movie ever made for more than a decade.

"It didn't seem iconic from my point of view," he told the outlet. Hill also said he did background research on the real captain he was playing in "Titanic" and "thought I was doing him justice."

Hill had been scheduled to appear at Comic Con Liverpool this weekend along with several other "Lord of the Rings" stars. In a post on social media, the convention said it was "heartbroken" to hear about his passing, adding, "A great loss. Thinking of his family at this very sad time, and wishing them a lot of strength."

At the convention on Sunday, "The Lord of the Rings" stars Sean Astin, Elijah Wood, Billy Boyd and Dominic Monaghan paid tribute to their former co-star, according to video shared by ITV News.

"We love him," Astin said of the "funny" and "beautiful" actor, while Boyd said that no one "spoke (J. R. R.) Tolkien's words as great as" he did. "He was a wonderful man and he'll be sorely missed," Boyd added.

"Better Call Saul" star Michael McKean, who worked with Hill on the movie "True Crime," also paid tribute to the actor on social media. "A gent, of course," he posted on X. "Also funny, smart and flawless at the job. RIP, sir."
