What's it like to be booped by a leopard seal? Or dive with over 300 fin whales in Antarctica? And how do you keep your cool when filming underwater in one of the most challenging and remote places on earth, while tiger sharks patrol the shallows above you? At Wildscreen film festival, host Isla sat down with award winning film-maker and wildlife cameraman Bertie Gregory to chat about his new series, Epic Adventures, and go behind the scenes of episode 3, 'Shark Island', where Bertie searches for aggregations of scalloped hammerheads in the Cocos Islands. We talk about insane wildlife spectacles, how to interact with and portray large predators responsibly, and telling stories about some of the issues facing the natural world with hope and optimism. 
Epic Adventures is now streaming on Disney Plus. You can also follow Bertie's escapades on instagram (@bertiegregory).
