Leonardo DiCaprio has offered his take on an age-old Titanic question related to his character Jack Dawson’s death.

Fans of James Cameron’s 1997 movie have debated for years on whether Dawson could have fit on the door used by Rose DeWitt-Bukater to keep out of the frigid Atlantic waters after the ship sank – and whether Dawson could thus have survived the Titanic’s sinking.

MTV News correspondent Josh Horowitz asked DiCpario about the infamous door in a recent interview as part of the promo tour for Once Upon a Time in Hollywood.

When asked whether Dawson could have fit on the door, DiCaprio, arms crossed, gazed towards the ground and said with faux resentment: “I have no comment” – before laughing along with Horowitz.

DiCaprio’s Once Upon a Time in Hollywood co-stars Brad Pitt and Margot Robbie chimed in, with Pitt pledging to “go back and look” at the film.

“That is the biggest controversy I think, in modern cinema,” said Robbie.

Pitt then leaned towards DiCaprio, asking him: “Could you have squeezed there? You could have, couldn’t you?” and Robbie asked whether DiCaprio had asked to make the door smaller – presumably so that Dawson’s decision to remain in the ocean would seem more realistic.

Both times, DiCaprio reiterated between giggles that he had no comment.

Once Upon a Time in Hollywood, Quentin Tarantino’s latest movie, will be released on 26 July in the US and 14 August in the UK.
