Bratislava, August 27 (TASR) - The documentary 'Theory of Happiness by Rybansky' directed by Slovak filmmaker Rasto Hatiar has won the Grand Prix at the 35th international mountain and mountaineering film festival in Teplice nad Metuji in the Czech Republic, TASR learnt on Monday. A total of 41 movies from all around the world portraying mountaineering and sports themes competed in the prestigious film festival, which took place between August 23-26. "I would be delighted to have received any honourable acknowledgement and I cherished a small hope to get one, but I didn't think that this story could appeal to the jury so much that it would crown it with the highest prize. I appreciate the award and I'm happy that not only great achievements and extreme adventures were awarded, but also the ordinary story of a modest and excellent man," said Hatiar. The 37-minute winning documentary is about the contrast of generations and their mutual understanding as well as about the poetry of climbing. 'Theory of Happiness by Rybansky' depicts former climber Lubo Rybansky who wants to visit for the last time the majestic wall of the former quarry at the Vtacnik Mountains in central Slovakia, where Rybansky along with his co-climber Rudo Pravda formed the basics of climbing in the 1970s.
