The National Audiovisual Archive or KAVA has quite interesting films running at Kino Orion during the spring 2011. For example Breakfast at Tiffany's on 11 March, Metropolis on 17 March etc. They also show children movies from time to time, for example The Lion King on 9 March. The last one is a play reserved mainly for pupils and students, but it is also possibly for a single person to buy tickets (however I've heard they are going to cancel the show if not enough persons are registrated by 18 February to koulut [at] kava.fi).
