Your code is mostly correct, except that you set the same mapper for two different actors so actually you are displaying twice the same geometry (line 19 to 24). Change:
# actors
actor1 = vtk.vtkActor()
actor1.SetMapper(mapper1)
actor2 = vtk.vtkActor()
actor2.SetMapper(mapper1)
to:
# actors
actor1 = vtk.vtkActor()
actor1.SetMapper(mapper1)
actor2 = vtk.vtkActor()
actor2.SetMapper(mapper2)
And it will work.
