Baron Bror von Blixen (Klaus Maria Brandauer) is a tiny bit miffed that his estranged wife Karen Blixen (Meryl Streep) has taken Denys Finch Hatton (Robert Redford) as her lover.
Brandauer to Redford: “You might’ve asked, Denys.”
Redford to Brandauer: “I did. She said yes.”
Redford was around 46 when Out of Africa was filmed; Streep was 34.
The Out of Africa screenplay is credited to Kurt Luedtke, but the above exchange was almost certainly penned by Sydney Pollack pinch-hitter David Rayfiel.
