In a recently released Titanic featurette, director James Cameron talks up the skill of the then-19-year-old Kate Winslet and reveals the young actress' original screen test. While it's fun to see a pre-Titanic Kate, the scene itself is stolen by someone else entirely — Jeremy Sisto (A.K.A. Elton from Clueless and Billy from Six Feet Under) was brought in to read for Jack Dawson, the role eventually won by Leonardo DiCaprio. It's probably for the best. If Elton was willing to leave Cher in a parking lot, he definitely would have let Rose sink to the bottom of the ocean.
