I never actually saw this live-action movie but I remember seeing a trailer of it on Cartoon Network once a few years ago. It was live-action. From what I remember, one minute, a boy sees and says: “Hello, Fox.” to a fox he comes across in the woods and then, the next minute, the fox suddenly replies with a rough/raspy voice and somewhat malicious grin on his face: “Hello, boy.” that suddenly shocks the boy.
Note: It is NOT The Little Prince.
Please, let me know ASAP.
