The now 36-year-old actress fought hard for the part however, sending the 58-year-old director a rose with a note that read, "I'm ready."u00a0The video footage shows her, dressed in period clothes and standing in a set of her cabin room, and reading out a lengthy scene which includes lines that were included in the movie, the Daily Mail reported.

It was the first real scene between her and Jack Dawson, for which ‘Clueless' actor Jeremy Sisto was auditioning.u00a0In the video, she is seen verbally sparring with Sisto in one part, while another sees her crying during a tender moment with her potential leading man.

Earlier this year, while recounting her time on the movie, she told USA Today, "I'm sure I wasn't really a very good actress."u00a0However, Cameron clearly thought otherwise and promptly signed her up.

Cameron later said about her casting, "A 19-year-old girl who was going to carry a film of that scale on her shoulders, it's a huge responsibility."u00a0"You're standing on set surrounded by 2,000 extras and all the lights and cameras are pointed at you. If you don't pull it off, it doesn't work.

"A lot of people would have imploded at that, but she didn't," he added.u00a0The blockbuster grossed over 2 billion dollars at the worldwide box office, and is the second most successful film of all time, behind Cameron's 2009 ‘Avatar.'u00a0
