Instead of movies or music:
Once we have immediate needs sorted out, a flute can be made from bamboo for our musical needs. We will be much too busy surviving day to day to miss watching movies. Instead, I would prefer to have at least one of my knives, and an ax, hatchet, or at least a saw if you're gonna dump me out on a deserted island. (which I could probably get into, by the way.) A few zip ties, paracord to use for making snare traps and binding limbs together for the hut, and a ferrocerium rod if at all possible.
As for which character from Gilligan's Island I would want to bring along...while Ginger is the gorgeous movie star she seems shallow, so I would likely choose Mary Ann because I believe she would be much more interesting to talk with, and she seems to be more capable and down to earth. I think she would be more likely to help us thrive in the elements, just going by the roles played on the TV show. Just for kicks I would likely request Gilligan as well, because laughter will be an important asset to thriving while stranded.
P.S. I would also need to smuggle in my dog, Sadie. She can help us find the elusive wild hog that we will roast to celebrate the end of rainy season. I would find it difficult to thrive without her there with me.
