Multiple dogs were utilized for the main cast members. “We had the hero for the closeups, and if there was any action required then we would typically have a stunt double. I would give a large appreciation to Mark Forbes and his team because what they were able to accomplish through training was remarkable. It exceeded my expectations in almost every area. For the spaghetti scene when Lady and Tramp are sitting down and there is the cute push over of the last meatball by Tramp to Lady, they trained Monte who was Tramp to actually do that and he was phenomenal. It was brilliant reference that couldn’t be used in the final because we had to add more to the action.”
A significant amount of the final footage was captured practically. “We were fortunate in the training and selection of the dogs to be able to capture all the nonvisual effects without issue,” reveals Weaver. “Then in the visual effects world we were able to get away with 25% to 30% of the real dog’s actions where we could be satisfied with rotomating the dog and replacing a CG version that looked exactly like the live-action dog, except that they had to focus in one type of performance or adding dialogue. The hero dogs were built to the fidelity, so the camera could be inches away and it would be photorealistic.
“No expense was spared in the details that we did on Lady, Tramp, Peg and Bull,” adds Weaver. “They were full 3D models. These dogs could be oriented in any fashion to camera and would hold up fine.” No major issues were had with the fur simulations. “We had one sequence on top of the ferryboat where the real dogs were up there for reference and leashed down for safety. Replicating how the wind moved across the fur was difficult, but nothing that was excruciating or painful. These days most of the main houses doing visual effects work have engines that are capable of doing photorealistic simulations of fur in a short order, but it’s mostly due to the artistic endeavors that make it believable. It either comes together easily or not easily depending on that person’s sensibility.”
