What happens to your memories if nobody shares them with you? Does it make them less real? Austrian painter and video artist Kevin Kopacka and his twin brother, documentary filmmaker Raoul Kopacka, try to answer this question in their movie “For Those Who Still Exist”. Starting point is the memory of one summer, when the 10-year-old Kevin befriended a boy called Patrick Lurzing. The two of them spent most of the days at the local playground - until one day, Patrick didn’t show up. Or did he never exist? Although Kevin’s memories of his friend are vivid, neither his twin brother nor other childhood friends can remember ever meeting a boy called Patrick Lurzing.
