So before you think of killing Hitler, or shagging Helen of Troy, remember that, as James told Tim during their cozy Ted Talk on Time Travel, you can’t. There’s also the added caveat of how you, or the person that’s taking you through time, can only go places that the traveler has been before, and can remember. However, there is the fact that unless you’re a male member of the Lake bloodline, or one decides to take you on a trip through time, you can’t make the big jump. So on the positive side of things, About Time doesn’t need any expensive time travel effects or vehicles to get to where it’s going. Which means that technically, the vehicle/conduit of time travel in this film is literally, the traveler’s own body. In an ingenious twist, the Lake men can only travel through their own personal existence and experiences. These particular conditions lead to the greatest limitation of About Time’s premise. Then you clench your fists… think of the moment you’re going to, and you’ll find yourself there. You go into a dark place, big cupboards are very useful, generally. According to Tim’s father, James, this is how you time travel: And the key to making sure you get to where you want to go is a skill any young person can clearly master: concentration. The time travel in About Time has to be one of the simplest methods ever employed in the history of temporal travel.
