This madcap, sci-fi time-travel film set in the 1990s details a plot by neo-Nazis to journey back in time to furnish Hitler with the hydrogen bomb and change the course of history. Polák (Ikarie XB 1) fuses the delightfully silly with the ingenious, the fantastical trappings of science fiction with the physical reality of then present-day Prague, all accompanied by a wonderfully lively score by composer Karel Svoboda. As characters move dizzyingly back and forth across time, encountering earlier and later versions of themselves, the paradoxes pile up and history stands on a precipice.
