Bob Hope recalled that during the scene where he and Bing Crosby were bedding down beside their cabin in the Klondike, they were to be joined by a bear. They were told that the bear was tame and its trainer would always be nearby. Against their better judgment they went along with it. However, when the cameras started filming, the bear ambled over to Hope and, instead of lying down next to him like it was supposed to, the animal sniffed him and started growling. Hope and Crosby immediately stopped the scene and refused to work with the bear any longer, despite the trainer's protestations that it was tame and harmless. The next day the bear attacked its trainer and tore his arm off.
This is the only one of the seven "Road" pictures in which Bing Crosby and Bob Hope do not do their famous "patty-cake" routine.
At one point Bob Hope remarks that Bing Crosby's voice is "just right for selling cheese". Crosby at the time was singing on the radio on the "Kraft Radio Show", whose sponsor was a company that made cheese.
Writers Norman Panama and Melvin Frank were having trouble getting the script approved by the three main stars, all of whom were prestigious in their own right and wanted the most screen presence. When these group script negotiations broke down, Panama and Frank held individual conferences with each of the stars, explaining how the script would highlight that star (the one being met with at the time) more than the others. This approach worked, and the script was finally approved.
