Story seems to extract many elements from "The Void Captain's Tale"

Rating: 6/10 (27 December 2016)

While watching the movie I couldn't help but recall a 1983 SY novel by Norman Spinrad called "The Void Captains Tale". This is especially true when the two characters decide to take an exterior ship walk while traveling at half the speed of light.
The Void Captain's Tale begins with a nice description of the infancy of warp space drive in which the only persons foolhardy enough to attempt such travel, are the lifestyles of the rich and famous. It is also the pent ultimate in "heroics" as it symbolizes human mastery over the universe that is forever expanding. It is Humanity's shining hour; it is humanity's Raison d'etre. Genro, the Captain of the pleasure and luxury liner, has erroneously met his Void Pilot in dry dock, which turns out to be his undoing, as the Void Pilots are always the unknown members of the complement. Their job, is to be literally inserted into the circuit that will allow the ship to jump x number of warps, making interstellar travel possible. If you want to read a good SY, I suggest digging up a copy of the book.
