Ana y Bruno
It took 13 years to make, cost 100 million pesos, won a whole bunch of awards, bombed spectacularly at the Mexican box office, and—most importantly—Guillermo del Toro and Alfonso Cuarón vouch for it: Ana y Bruno, an animated short about a spooky girl’s adventures with creepy critters. Imagine Tim Burton before he left Disney, working for Pixar before they joined Disney.
