1 - не refers to the verb; 2 - movies in general, not a specific one; 3 - two options are possible here: a) the reflexive verb нравиться requires Dative case (as in my correction above) or b) мои братья (Nominative case) любят смотреть фильмы (=interchangeable); 4 - Играть в игры, футбол etc., but играть на гитаре, пианино etc.; 5 - в прошлом году/месяце, но НА прошлой неделе; 6 - instrumental case "лучшим фильмом для меня был", sounds really natural! 7 - there is a fixed phrase/collocation "ради денег"; 8 - "и" is usually used for listing, here we better use "a" that stands for juxtaposition; 9 - there is no such a word as быграть. If you can tell me this phrase in English, I could help you with the correct translation; 10 - 'вспоминать to recall' sounds more natural; 11 - Donald Trump is a proper name, quotation marks are not required; 12 -"Я не работаю ради денег, я работаю 'ради + noun in Genitive' OR ',чтобы + verb in its infinitive form'. 13 - Мне нравится has Dative pronoun again; 14 - I would split the last sentence like this. The second part confuses me though
