All the characters from the 1997 film remain the same. The fictional ones belong to the Director James Cameron. I only own fictional characters that are not into the motion picture.
Here are a few gifs for you to get an idea of what my characters look like, but feel free to imagine them the way you like through your reading.
More will be added if needed.
Jennifer Lawrence as Lily Andrews
Victor Garber as Thomas Andrews
Jason Barry as Tommy Ryan
Pedro Alonso as Alfonso de Formosa
Jessica Brown Findlay as Josephine Perkins
Young Liam Aiken as Tiny Tim
