The main Theater Potdamerplatz is 15 mins away and many theaters in F-hain and Kreuzberg you can also see Berlinale movies.
Me and my flat mate we both studied film and photography. We can give you more information about Berlinale if you needed.
Kreuzberg is really great location. If you are into about 'Toand day Berlin'. My flat is just one minute from U8 Schönleinstr and you will have the sunny 30m2 room with a super king size bed. It has the beautiful open kitchen where you can chill.
