"Exclusive: Animal trainer Jo Vaughan talks to Total Film about the challenges of a big Marvel set and the moggies' lengthy training"

""We would have one of us standing in a [green or blue] suit while doing the action with the cat. We had a three-month training period," she says. "I read through the script, and marked down all the actions that the cat needed to do. These cats go onto set knowing everything that they're going to do. When we come to shoot, we break it down day-by-day. The day before we will prep what we’re going to do the next day so it's fresh in their mind.""

"Nemo and Tango, two orange tabbies, played feline-looking Flerken Goose, and each of them had a particular set of skills they brought to their paw-formances. "Nemo was better at running and jumping. Tango was the hero face of Goose. Whenever we did close ups, wherever possible, it would always be Tango. The naughtiest thing one of them did happened when we were on one of the sets where the ground was quite gravelly. We were all ready to go and it was just a giant cat-litter box. He didn't go to the toilet on set, but he came out and just started rolling around in it straight away. "

""The most challenging aspect of training a cat is the enormity of the sets, the huge crew, and time constraints. It's a lot for a cat. But they did us proud – as did the ten kittens." Yep, you read that right... there are Flerken babies in this movie, too."
