السلام عليكم the first thing that comes to mind, you can take the first one writen by Anas, we can use another one: أَوَّلُ شَيْءٍ يُرَاوِدُنِي فِي ذِهْنِي or أَوَّلُ شَيْءٍ يُبَادِرُ ذِهْنِي For the second: we have a lot in common. The last one said, it's actually using in an accent, in MSA, we have to say: هناك أَشياءٌ كثِيرة مشتركةَ بينَنا the 3th, you can also take it from Anas, and we can also say: هذا أفضلُ فيلمٍ البَتَّةَ

The first thing that comes to mind : اول شيء يخطر ببالي 'awal shai' yakhtor be-bali' We have a lot in common: في اشياء كثير مشتركة بيننا" fe ashia kather moshtaraki bainana" That's the best movie ever made: هذا افضل فيلم على الاطلاق " hatha afdal film ala el-etlak"
