According to one theory surrounding the movie Titanic, Jack Dawson was actually a time traveller. What was his mission you ask? To save Rose from committing suicide and altering the future forever. It’s not as farfetched as you may first think. Just think about it for a moment, if Rose had jumped off the back of the ship and into the ice cold waters of the North Atlantic then the ship would have turned around to look for her and, consequently, the Titanic would, in all likelihood, never have hit that infamous iceberg. History would have been altered forever.
Let us consider the evidence supporting the time traveller hypothesis. Firstly, Jack had to hustle and gamble for a ticket to get on board the Titanic. And why is this? Well, because he had no currency from that time period. Alright, we agree, it’s a bit suspicious and there could be other reasons, but it’s not totally out of the realm of possibility, right? Well, if we consider the following facts then time travel definitely begins to seem the most likely explanation. You see, Jack mentions fishing at Lake Wissota; this is a man-made lake that was built in 1917, 5 whole years after the Titanic sank. Moreover, his haircut and rucksack were completely out of place for the era, rucksacks weren’t popularised until the 1930s. And, finally, in the classic “King of the world” scene, Jack tells Rose that he’ll take her to the Santa Monica Pier where they’ll “ride on the roller coaster until we throw up”. That’s romantic … until you realise that in 1912 there was no roller coaster on the Santa Monica Pier. It wouldn’t even be built until 1916.
We can only logically conclude that Jack must be a time traveller.
