THE GREAT ADVENTURE - It’s all shown in the poster. Jack Palance Town Boss, Joan Collins saloon girl with a heart of gold, an annoying kid and his wolf dog. Palance tries to steal the dog for his own purposes and Collins helps the kid get him back an exposes Palance as crook.
Buck at the Edge of Heaven is a Call of the Wild adaptation featuring John Savage, in a dual role, who seems to think he is in a junior high Shakespeare play as he overacts shamelessly. There are a couple of Dell’Acquas and this one who looks like one but seems too young for a 1991 production, maybe Aldo?
I must say there are a lot of ending credits so he may be someone else entirely.
