Hold onto any door you can find with arguably enough room for two people because we've got some news for you.

During her appearance on The Late Show With Stephen Colbert on Friday, Kate Winslet revealed that before Leonardo DiCaprio landed the career-altering role of Jack Dawson in 1997's Titanic, Matthew McConaughey came incredibly close to getting the job. "I auditioned with Matthew, isn't that weird?" Winslet confessed. "Never said that in public before."

Luckily, James Cameron, writer, producer and director for Titanic, insisted on having DiCaprio play opposite Winslet because he realized what we have now known for the last two decades—the chemistry between Kate and Leo is undeniable. "I auditioned with Matthew, which was completely fantastic," she added. "It just wouldn't have been the whole, Jack and Rose, Kate and Leo thing."

Winslet added another wrinkle to the widely debated scene where Rose wouldn't move over just a couple inches to the left to help save Jack's life, arguing that Leo's character should have tried harder to get on the door.

"He just should have tried harder to get on that door, because I think we would have [fit]," Kate said.
