Harry and the Hendersons
Returning from a hunting trip in the forest, the Henderson family's car hits an animal in the road. At first they fear it was a man, but when they examine the "body" they find it's a "bigfoot". They think it's dead so they decide to take it home (there could be some money in this). As you guessed, it isn't dead. Far from being the ferocious monster they fear "Harry" to be, he's a friendly giant.

The Force on Thunder Mountain
Thunder Mountain somewhere in the American wilderness, has a reputation that has scared away travellers, both white and Indian, for hundreds of years. Undaunted by the ghost stories surrounding the mountain, a father decides it's just the place for him and his son to go camping and do a little bonding. Strange voices and stranger footprints around their campground try to warn the pair away, but Dad is unconcerned and blithely pushes on. Eventually, however, the two come face to face with the force standing guard over this forbidden mountain.
