Last summer a friend of mine was watching TV and at one point he turned and a bear was watching him through the patio door - he was on his porch. Yes, they are normally scared by humans but with lack of food due to late spring you can see them these days roaming in backyards for snacks.
Regarding the movie I think the guy knew that a bear was in that area at that hour otherwise he wouldn't decide to stay off the road before the bear arrived. And I think the bear knew he was there - he was sniffing the old traces of the guy I think - before the man made his show. Some would say that this is a stalking behaviour in a way. All my hunting friends have a bear spray with them, even when they go with a bike on trails. Over protective? Maybe, but last year 2 grizzlies were seen in a courtyard in the middle of the day - and it is black bear country, not a grizzly known area. I enjoy the outdoor, but better safe than sorry. And I think the rule here is to be 2 when going for bear - at least on paper.
