At certain "locations" in spacetime, there is a wormhole such that, if you jump in, you'll emerge at some point in the past. To the best of our knowledge, these time loops are not ruled out by the laws of physics.
About Time is a romantic comedy -- a genre I feel is fading in quality and relevance as repetition, the modern realities of relationships, and the myth of couples living "happily ever after" have exposed the shallowness of the genre's clichés.
