The Studios wanted Matthew McConaughey for the role of Jack Dawson, the attractive everyman in Titanic, but James Cameron insisted on Leonardo DiCaprio as his leading man, saying he soon realised the actor had something special.
“Leonardo was on a list of names. I didn't know him and I’d only seen him in Gilbert Grape so I didn't really know what to expect,” said Cameron.
But I noticed that when he came in for the first meeting... all the women in the building were in the room. (I thought) This is a little odd, you know.”
The director’s instincts were probably sound as the movie, the biggest grossing film of all time, netted 11 Oscars, including Best Director, although it didn’t gain any acting awards.
