It'll happen to you, if you're lucky: You'll be in the shower, and you'll notice a liver spot on the back of your hand where there wasn't one before. It's just another sign that you're getting older, and considering that over 95 million Americans are currently over the age of 50, you're obviously not alone. The third annual Legacy Film Festival on Aging aims to entertain and educate audiences of every demographic about what it means to age, and how to go about doing it in a way that doesn't make you feel — for want of a better word — old. Taking place in the Coppola Theater at San Francisco State University, the festival offers 24 films of varying lengths from seven countries, kicking off with San Francisco-based filmmaker Sari Gilman's Oscar-nominated documentary King's Point, a look at the denizens of a Florida retirement resort. Gilman will be on hand for a Q&A to discuss her film, which recently won Best Documentary Short at the San Francisco International Film Festival. Another must-see is Icelandic director Fridrik Thor Fridriksson's quasi-autobiographical Mamma Gógó, about a filmmaker dealing with his mother's descent into Alzheimer's — as well as the fact that audiences are avoiding his films about aging. Here's to hoping festivals like this change that.
