    Since you're bringing up scientific realism, the engines (apparently fusion) actually only need to fire up to get the planet up to speed rather than for the duration of the journey (Newton's laws and all that), once it's moving at say 1,200,000 mph (4.5 light years / 2500 years) it won't need to fire up again until they need to brake! As it takes roughly 354 days to accelerate to light speed at 1g (9.81m/s) the engines would only need to run for a few tens of years (obviously still needs to tick over to provide heat and energy so the folks on the 'wandering earth' don't freeze).

    Lots of other scientific issues with the movie, but fuel consumption shouldn't be one of them! Well a bit of kudos to them at least they didn't do the worm hole thing :)

    I didn't see movie yet, but for my understanding, you don't need fuel for 2500 years, you just need enough fuel to accelerate the earth to a speed of approximately ~500 km/s, which 1.6 promille of the speed of light, and then to decelerate the earth, when the earth nears Proxima Centauri, for a 2500 years long journey to Proxima Centauri. The acceleration- and decelerationphase maybe takes a couple of years.
    Most of time the earth will travel through interstellar space.

    Thanks for the link. I watched it again. I only wish someone posted the link earlier.
    The first time I watched it, I drove 2hrs to Dunedin than a two hour flight to Auckland. I was quite surprised as there was under 100 people watching the movie which was quite surprising as there's about 250,000 Chinese in Akld. I guess they must have your link as well.
