The Door (Die Tür) is a German film that follows a man who finds a door that sends him 5 years into the past.
After finding his daughter dead in the swimming pool following his affair with a neighbour, David (Mads Mikkelsen) finds himself out of luck with his ex-wife (Jessica Schwarz) as the film forwards by 5 years.
He attempts suicide, but following his rescue he finds a door that sends him back to the time of his daughter's death. He saves her but kills his past self in an ensuing struggle. As he tries to adapt to replace himself in his past life, all is not as it seems.
Going back to visit a loved one is something that is a very common theme in the world of time-travel, so when I read the blurb of The Door, I wasn't overly excited for fear of it being yet another overly-romantic film. A romantic film it is most certainly not.
What The Door does have is a very interesting plot concept. Its central object is, of course, the time-travel door. While it is not often seen being used throughout the film, the way that the writers have made a grand use of it being there and incorporated it intricately into the storyline is absolutely superb.
Mads Mikkelsen, who is more famous for his roles in King Arthur and as a James Bond villain, excels as David and as a man torn between the life he left behind and the life he has now re-entered. The inadvertently sinister moments are separated well from the obvious pleasure at being able to hold his previous dead daughter in his arms once more.
While there are a number of unexplained plot holes (especially when he meets his previous self), it is a shame that The Door has not gained more popularity as it is one of the best German films that I have seen for a long, long time.
