Star Trek Beyond is missing a character who seemed like a new part of the team (and eventual spouse of Captain Kirk) at the end of Star Trek Into Darkness: Dr. Carol Marcus (Alice Eve). Simon Pegg — film co-writer and Montgomery Scott(y) actor — explained the absence of Dr. Marcus in the very rushed script while he was a guest on Episode 13 of the Star Trek Podcast, as transcribed by io9:
“We thought rather than have Carol Marcus be not used to a reasonable capacity, let’s just not include her, have her be alive, in canon, and be ready to come back at any time,” he concluded. They did try to give a reason for her absence. “I think we had some lines to explain her absence in one of the initial drafts that had her going off to start work on the Genesis project and do sort of very, very early research on that,” Pegg went on to explain. “But it didn’t make it into the final cut.”
This jibes with what director Justin Lin has said about how Beyond is ignoring several aspects of Darkness, including the cure for death in Khan’s blood, the ability to beam across entire galaxies, and, yes, the relationship between Kirk and Marcus. Sorry, Alice Eve fans, Dr. Marcus was off terraforming planets while Simon Pegg and Doug Jung were busy writing fan fiction about Jennifer Lawrence in Winter’s Bone.
