Kate Winslet fully agrees with the many Titanic fans who have noted that Jack (Leonardo DiCaprio) definitely could have fit on that floating piece of debris at the end of the Academy Award-winning 1997 film.

The actress stopped by The Late Show with Stephen Colbert on Tuesday, Sept. 24, to chat about her new film, Lee, and to mark the occasion, the show’s official TikTok account posted a hilarious throwback to Winslet’s December 2017 guest appearance.

At the time, Titanic was approaching its 20th anniversary, and Colbert peppered a delightfully game Winslet with questions from his staff about the James Cameron-directed film. One question took her Titanic character, Rose, to task for the scene in which she remains floating on an ornate wood panel after the titular ship has sunk, while DiCaprio’s Jack freezes to death in the icy water.

“In the famous line, you say ‘I’ll never let you go, Jack,’ ” Colbert noted. “But you do!”

“I lied,” Winslet admitted. “I agree,” she added, earnestly facing the studio audience. “I lie. I fully lie. I hold my hand up, I let him go.”

“Plus, he just should have tried harder to get on that door,” she continued, referencing a slight flaw in the otherwise beloved film that many fans have pointed out over the decades since its release.

To prove the point, Winslet then suggested that she and Colbert reenact the scene, with her splayed across his desk and the host clasping her hands from the floor below.

“Promise me, Rose!” Colbert said. “Let me get up on that door with you!”

“Come on, darling! There’s room for two!” Winslet replied.

Colbert then hopped up on the desk alongside the Oscar winner as the audience cheered and Winslet triumphantly cried, “Yes!”

Earlier this year, the wood panel upon which Rose — but not Jack — floated was among a cache of historic Hollywood props that were up for auction. In a March 25 press release, auction house Heritage Auctions noted that the Titanic prop fetched the highest price, beating Indiana Jones’ whip, Princess Leia’s blaster and an ax from The Shining.

“The wood panel from Titanic that saved Rose — but, controversially, not Jack — was the king of the auction,” Heritage Auctions’ release read, getting in a dig at Winslet’s character, “realizing $718,750 to float to the top of the five-day event.” The prop is now on display at the Titanic Museum in Pigeon Forge, Tenn., before heading to the Titanic Museum in Branson, Mo.
