Filmmakers Marvi Lacar and Benjamin Lowy often take their two sons on the road to feed their curiosity. In “Back to the Mara,” they introduce the boys to the country that inspired their professional collaboration over ten years ago. This time around, and with the sponsorship from NatGeo Wild, Kaleb, 7 and Mateo, 9, led the way. The parents had front row seats to the boys’ exploration and discovery. The boys who are incessant, curious and talkative, asked about nature, life and everything else in between.
