from www.germanherald.com - Stars from a new blue movie based on sci-fi thriller Avatar were beseiged by goggle-eyed fans at a porn festival in Berlin, Germany.

The performers - who spent four hours in make up donning blue paint and prosthetic ears - boldy go where the original movie didn't dare in the raunchy space romp.

And DVDs of the movie - This Ain't Avatar XXX - sold out within an hour, say organisers.

Other festival hits at the Venus Fair included a bizarre fetish horse costume complete with reins, bit and bridle.
