Premise: Ręce do góry (known in its subitled English version as Hands Up!) is a Polish drama film directed by Jerzy Skolimowski. It is the fourth of a series of semi-autobiographical films in which Skolimowski himself plays his "alter ego", Andrzej Leszczyc. At the time it was banned in Poland, under the Communist regime, for 18 years because it depicted the Stalinist past.
Hypothesis: Andrzej Leszczyc is the alter ego of Jerzy Skolimowski.
