July 5 marks the beginning of National Geographic’s SharkFest, an annual televised celebration of nature’s most perfect aquatic killing machines. The event will span for six weeks, contain over 80 hours of content across four networks (National Geographic, Nat Geo WILD, Nat Geo Mundo, and Disney XD), and it’s all getting started with a new special from the God of Thunder, himself. Shark Beach with Chris Hemsworth will air at 9 p.m. ET, July 5 on National Geographic. The one-hour special will follow the Australian movie star as he seeks to understand how mankind can live more harmoniously with sharks. The documentary comes from Nutopia (One Strange Rock) and features shark conversationalist icon Valerie Taylor, who will guide Hemsworth on a shark diving experience. You can check out the first trailer below. Shark Beach with Chris Hemsworth was announced in August of last year which means Marvel’s risk management legal team really must have been asleep at the wheel. Perhaps that’s why Hemsworth got so inconceivably shredded for Love and Thunder – he needed to fend off some sharks. Here is the rest of this year’s SharkFest programming with all descriptions provided by National Geographic.
