I took this video with an iPhone in January 2014 in Rwanda. The first 9 minutes feature a cute baby gorilla playing with its mother. The action starts around 10:10. The large male gorilla marches in and steps on my chest ... Our guides think I had gotten too close to the baby (iPhones couldn't zoom on video back then), so the large male was telling me to back off. The guides estimate he weighs 280kg. Maybe they could have warned me before he entered the frame?
