James Cameron's completely immersive spectacle "Avatar" may have been a little too real for some fans who say they have experienced depression and suicidal thoughts after seeing the film because they long to enjoy the beauty of the alien world Pandora.

On the fan forum site "Avatar Forums," a topic thread entitled "Ways to cope with the depression of the dream of Pandora being intangible," has received more than 1,000 posts from people experiencing depression and fans trying to help them cope. The topic became so popular last month that forum administrator Philippe Baghdassarian had to create a second thread so people could continue to post their confused feelings about the movie.

"I wasn't depressed myself. In fact the movie made me happy ," Baghdassarian said. "But I can understand why it made people depressed. The movie was so beautiful and it showed something we don't have here on Earth. I think people saw we could be living in a completely different world and that caused them to be depressed."

1983: Apple releases the Lisa, the first commercial computer with a graphical user interface (GUI) – the advance that would finally make computers usable by people with no special training. It doesn’t sell well, but it does get Apple on the right development track, sparks the first of many brawls with perpetual rival Microsoft, and sets in motion the animus between Steve Jobs and John Scully that would frame the company’s history for a decade.
