The last film I watched was "fantastic critters, and where they inhabit". This movie is about what the main character wants to save, and save a fantastic world, among people. In this he is helped by two golduns, and a man. But that's what's stopping them. But in this they are hindered by the president/mayor of the city(countries.) Says these creatures are quite dangerous for World. That's why she starts to set up the creatures, which prevents her main character. I advise you to see it!

A=hv-eU=hc/λ-eU
A=6,6•10⁻³⁴•3•10⁸/500•10⁻⁹-1,6•10⁻¹⁹•0,8=3,96•10⁻¹⁹-1,28•10⁻¹⁹=2,68•10⁻¹⁹ Дж.
