This silly scene appears in the brand new trailer for "The Twilight Saga: Breaking Dawn -- Part 2," courtesy of Yahoo! Movies. The fourth and final installment in the popular "Twilight" franchise features Edward (Robert Pattinson) and newly vampiric Bella (Kristen Stewart) defending their newborn daughter Renesmee (newcomer Mackenzie Foy) from the Volturi.
Given the threat, they seek out help from werewolf Jacob (Taylor Lautner) and the various vampire clans scattered around the world. There's a huge battle, which means lots of CGI wolves and special effects.
But the graphic artists' greatest work is in the aforementioned mountain lion scene. Watch (and rewatch) it in all it's glory above, and check out more stills from the film below.
