Last year, the footage above was posted on YouTube featuring a battle between lions, buffalo and crocodlies while on safari at South Africa’s Kruger National Park. As of today, it’s been viewed more than 30,345,229. Seeing a great opportunity to capitalize on what’s being regarded an “internet phenomenon,” National Geographic turned “The Battle At Kruger” into a documentary that airs this Sunday, that offers a behind-the-scenes look at how Jason Schlosberg and David Budzinski attained the riveting multi-animal attack video.
