A zoo veterinarian gets caught up in a grisly adventure as she finds herself leading the city-wide hunt for a monstrous lion terrorizing the Dutch capital of Amsterdam.
Realizing that using a real, living lion was not possible, and since filming with wildlife is prohibited in the Amsterdam city area, the crew contacted Dutch animation director Erik De Boer, whose company was responsible for the computer-generated tiger in Life of Pi (2012). However, De Boer calculated that one scene alone with a fully computer-generated lion would cost about a million Euros (one-third of the entire budget). The crew then turned to a Dutch special effects company, who built a very detailed, manually operated animatronic lion for the close-up scenes. A computer-generated lion was used for a few scenes that showed the creature in full.
