Where to watch Titanic ↓Six Months Of Titanic Obsession
Cameron didn't start writing until he was done researching. He spent six months studying the crew and passengers and built a detailed timeline that historical experts verified.
Borrowed From A Night To Remember
Cameron grew up on 1958's A Night To Remember and lifted from it. He borrowed dialogue and scenes like the steerage party and musicians playing as the ship sank.

Old Rose Was The Framing Device
The romance needed weight across decades, so Cameron invented elderly Rose. The framing made the intervening years feel emotionally significant to the audience.

DiCaprio Was A Terrible First Audition
Leonardo DiCaprio didn't want the role and was unfocused during his first romantic scene read. Cameron still saw potential and pictured Jack like James Stewart or Gregory Peck, not brooding and neurotic.
Leo Later Regretted Titanic
DiCaprio turned down Boogie Nights to do Titanic. In 2025 he said he regretted it, calling Boogie Nights a profound film of his generation.
Winslet Mailed Cameron A Real Rose
Kate Winslet campaigned hard for Rose from England with daily notes. She later sent a single rose with a card signed From Your Rose and finally won him over.
McConaughey Lost Jack Over Accent
Matthew McConaughey auditioned for Jack but was disregarded. He refused to change his Southern accent, so Cameron moved on.
Crudup Said No To Jack On Purpose
Billy Crudup turned down an audition for Jack to star in Without Limits. In 2000 he said Titanic would not have been as successful if he had accepted.
Gloria Stuart Was A Complete Unknown To Cameron
Cameron asked casting director Mali Finn to find retired Hollywood Golden Age actresses for elderly Rose. He cast 87 year old Gloria Stuart even though he did not initially know who she was.
Tom Cruise Was Too Pricey For Jack
Tom Cruise was interested in playing Jack, but his asking price was too high for Cameron to consider.
