I still remember we had some shots where all the elephants walked together, and we could feel the ground shake," he recalled.Rana added: "That was the moment I actually felt their mighty presence. 'Haathi Mere Saathi' gave me a chance to rekindle my love for nature."'Haathi Mere Saathi' will premiere on Zee Cinema on September 18.
