Hepburn, much like her character, looked on Bogart and Huston's alcoholic regimen with disdain. She made a point of drinking only water, which ironically made her sick. Bogart and Huston, on the other hand, were fine. "All I ate was baked beans, canned asparagus and Scotch whisky," Bogart later recalled. "Whenever a fly bit Huston or me, it dropped dead." The restored print highlights just how green and gaunt Hepburn looked. During some scenes, a bucket was kept off-camera for her to throw up into between takes.
"It was very tough for Katie Hepburn," says Allen. "She had very definite ideas about everything and everybody. One day we were shooting a complicated shot and John said, 'Print it,' and she said, 'You weren't even watching!' John said, 'But I was listening.' 'But you weren't watching,' she insisted and demanded they do it again. To turn the whole flotilla around and come back down the river took hours. John did shoot another take, but we used the original anyway."

There are tales of dysentery, diarrhoea and other tropical ailments, not to mention soldier ants, hippos, black mambas and crocodiles. But adversity drew everyone together. Bogart helped pull the African Queen out of the river when it sank one night, while Bacall mucked in with the catering. She and Hepburn became lifelong friends, and Hepburn ultimately came to admire Huston. Their relationship even became flirtatious, judging by the memoir she wrote later, entitled The Making of the African Queen, or How I Went to Africa With Bogart, Bacall and Huston and Almost Lost My Mind.

This admiration was mutual, says Anjelica. "I remember, towards the end of his life, we were all having dinner and Dad started to talk about The African Queen. He said, 'Katie was the best female friend I've ever had in my life.' And Lauren Bacall, this little voice at the end of table, piped up, 'Well what about me, John?' And he said, 'Oh honey, you were married to Bogey.'"
