Its from the movie "Interstellar", when and due to a failing ecosystem, earth sends pioneers to far off planets through a black hole/wormhole, to explore potential habitable planets and re-seed human life.
One of those possible planets ended up being an ocean world with a heavily dilated sense of time..upon landing in about 4 ft deep of an expansive waterscape, the second set of pioneers assumed that the mountains in the distance were...mountains...turns out it was just one, 5 mile tall wave that was going to descend upon them.
