The Time Traveler's Wife (2009) - spoilers

[Don H]

Time travel occurs in many movies, but this one gives a new slant on it - it
is due to a genetic anomaly. How? Well, that is only touched on, while the
romantic element predominates.
Henry (Eric Bana) is the person so afflicted, and he comes and goes, like
the Cheshire Cat, and, like The Terminator, naked - having to steal clothes
every time he pops up in a different time-period.
He can't alter looming disastrous events, but stealing clothes, complete
with wallet, etc, has no seeming impact on the victim's life.
Time travel is a pleasing fiction, but in actual fact it is impossible.
Why? Because if we all are part of a huge chain of causal consequences, an
integral part, then you'd have to reverse all of that to reverse time
itself. Having a single person, "go back in time", even as observer, would
violate the laws of physics.
Can you invent a time machine (or genetic anomaly)? No. The
chrono-gene is located - where?
Still, this movie succeeds, given its basic assumptions, and has
sufficient drama, romance, and science fiction, to make an integrated whole.
Just as well, perhaps, we don't know our own future, eg. date of
death - ignorance is bliss.
The TimeTraveler's long-suffering wife is Clare (Rachel McAdams),
though she (and he) are played by younger versions, as the plot demands.
