Hi everyone!

I need some help:

- I'd like to know when I should use "what about you?" x "how about you?", meaning "e você?".

- How can I say "Vou assistir o filme no final de semana e depois te digo o que achei", in English? Would it be correct to say "I'm going to watch the film on the weekend and then I'll tell you my impressions"? How/what about "I'm going to see the film this weekend and after I'll tell you what I found about it"?
