The upcoming fact might suggest that the main characters in the movie are actually clairvoyant. “Jack” wants to take “Rose” to the Santa Monica Pier to ride the roller coaster with her. The interesting aspect here is, that said roller coaster was opened in 1916, four years after the sinking of the Titanic. Also, “Rose” quotes works by Siegmund Freud, which were published years after the tragedy of the Titanic.
