The lion in the movie is a mixture of reality and puppetry. Like in one scene where Hub, Garth, & Walter were looking at it, they weren't really looking at the lion. From inside the crate, they were looking at the puppet lion moving the head like it was actually moving.
In the bar fight the shotgun is cycled open and closed to chamber a shell and get attention. In following camera shot action is open (wooden forearm to rear of barrel). For remaining scenes the action is again closed (wooden forearm back to front of barrel).
In the final scene before Walter hears the helicopter his hair is perfectly still and then begins blow as if the helicopter is right over him even though the helicopter has not yet appeared over the tree line.
When the lion is in the crate and they are going to shoot it you can see the chain holding the lion in the crate running down his chest partly exposed, they tried covering it up with fur, you can see it in several shots.
