Even, the Internet has it a Dr. Sean C. Solomon from MIT wrote “The Lunar Orbiter experiments vastly improved our knowledge of the Moon’s gravitational field … indicating the frightening possibility that the Moon might be hollow.” I haven't found the original source of this. Does anyone know it?
A more concrete treatment of the density distribution must await a more definitive determination of the lunar seismic velocity profile and, more importantly, a more accurate value for the Moon's moment of inertia. As long as workers active in the determination of the lunar gravitational field cannot agree on a value of C/MR² to within better than 1 or 2%, then firm handles on the nature of the Moon's upper mantle or tight constraints on the properties of a lunar core must elude us. The Lunar Orbiter experiments vastly improved our knowledge of the Moon's gravitational field, especially considering that the classical value for C/MR² indicated the frightening possibility that the Moon might be hollow. More accurate determination of the principal moments of inertia of the Moon, utilizing high-latitude and backside tracking data, should remain a high priority.

The quote is taken out of context from a 1974 paper by Dr. Sean C. Solomon: Density Within the Moon and Implications for Lunar Composition, The Moon, Volume 9, Issue 1-2, pp. 147-166.
Look for it on page 165 here.

What he's really doing is lamenting the inconsistent value of C/MR² in a humorous way while pointing out that the classical value could have led one to conclude that the Moon was hollow. I figured I'd actually track down the source because it's an oft repeated out of context quote (and usually worse with the purposefully misleading ellipsis) with no citation.
As for the movie. My wife and I saw it in IMAX a week or so ago and it was epic!

You've also probably heard about the anomalies detected by seismometers placed on the moon that indicate theres's something odd about its iternal structure. Even, the Internet has it a Dr. Sean C.

So comment about both hollow worlds and the movie or choose one! Synergy cannot be bad.

the movie was over 3 hours long and there was not a giant alien robot or even an alien to be found. If you can build a habitable space station, you can build one on earth. Just watch 'Under the Dome', or maybe not. So wait, they had to move to the space station because they ran out food on earth?
the length of the movie is 169 minutes, that's less than 3 hours, which is 180 minutes.
maybe they could have shown your mesmerising robot in that 11 minute gap...

it felt like 4.

Aliens, robots, space battles with an evil race from another dimension...boobs. Anything.

& I don't want to be rude or anything, but people who don't like Nolan's movies are very often narrow-minded and even stupid-ish.
So you'd better download Inception, The Prestige, Insomnia, Memento and you do start educating your sense for the cinema!
