At Karen and Denys's first safari dinner, Denys's fruit is partially peeled, then completely unpeeled, then fully peeled in different shots during their conversation.
When Karen Blixen is about to shoot the lion, blood is on the right side of her mouth, from biting her lip. Afterwards, when Denys wipes her mouth, the blood is on the left side.
When arriving in his new plane, Denys hands Karen Blixen his goggles twice. The goggles subsequently reappear and disappear several times.
Karen Blixen's champagne glass is empty when she slaps a rude man at the New Year's Eve party. Denys takes her arm and pulls her immediately onto the dance floor. When they dance, her glass has champagne in it.
When Karen undresses Denys in her bedroom, she unties his tie twice.
Karen met Finch-Hatton for the first time at the Muthaiga Club in 1918, not in the plains.
Finch-Hatton took up flying and became a safari guide after he moved in with Karen in 1926, not before they met.
The double-lever, rack-and-pinion "Wing" corkscrew has its origins in H.S. Heely's 1888 British patent on a corkscrew he called the A1 Heeley Double Lever. A version of the corkscrew reached the United States in 1930, but it was widespread in Europe before that.
The obvious use of blue screen backgrounds in the introductory scenes in Karen Blixen's room when the camera glides to the right of the screen and the movement of the exterior landscape does not match that of the camera, and minutes later before the Title Credits take place, Karen and her husband sit and talk on a tree branch, the background moves differently from the two characters sitting in front of it.
When Denys Finch Hatton brings a record player to Karen Blixen's home, he lowers his hand and the sound volume decreases. Volume was set at recording time, not at playback.
Karen offers the tribal chief a box of cigars made by the La Paz factory, in the Netherlands. That factory started exporting cigars in the 1960s.
The drummer at the New Year's Eve party uses contemporary nylon-tipped sticks.
The Mombasa-to-Nairobi railway is on the opposite side of the Ngong Hills. It doesn't travel through the Kenyan Rift Valley.
During the lion attack, Denys pulls an additional two spare cartridges from his belt as a ready reload. However, he carries them with his right hand, his trigger hand, which also is the hand needed to break the action to reload. No experienced double-gun hunter would do this. The two reload cartridges must be carried in the left hand, leaving the right hand free to manipulate the rifle.
As being cousins, one a Dane and the other a Swede, Karen and Bror most likely spoke Danish and Swedish to each other, not English. Danish and Swedish are mutually intelligible with each other due to the Scandinavian dialect continuum.
