The Museum Montanelli is a small museum - half a dozen rooms - which is used for temporary exhibitions. Until 25/10/2015 this is NaFilM! curated by Czech film studies students and intended to - one day - form the basis of a national film museum. While it's small, there's plenty there to entertain even if you know nothing about Czech film (which we didn't). There's a room devoted to sound effects used to accompany silent films - you can bang coconuts, crank up a wind machine and even race a moving train in order to rescue the heroine. There are some lovely 1930s posters, a screening room showing avant garde films of pre-war Prague and lots more about the technical aspect of film with plenty of buttons to press for people who like that sort of thing. And the curators are eager to talk to visitors. It makes a nice companion piece to the Special Effects Museum only a few minutes walk away.
