When Alex first meets Spencer at the bar, her champagne glass changes from her fight hand in front shots to her left hand from rear shots.
Banner begins cutting himself down from the rope but in the very last clip before the rope gets cut, you can clearly see the knife is still in his mouth.
Women were not allowed into the bar at the Muthaiga Club.
The country club - presumably the Muthaiga Club - has an electric ceiling fan in the upper veranda. Although electricity was first available in the commercial district of Nairobi town in 1908, power would not reach Muthaiga for years to come. The club, by the way, did not have a second story.
Alexandra ask "where does the next adventure takes you?" and Spencer replies "East". But they were in Nairobi and Spencer leaves to Serengeti, which is in the West from Nairobi.
When at the club, including when preparing to travel, Alexandra would definitely not have been wearing trousers.
