Is this a stupid thing to do (please help 10points to best answer!)?

ok well me and my friend are planing on going to see Hotel For Dogs on Saturday, and we are going to talk about it in homeroom to marrow. well this guy i like is in my homeroom and he sometimes comes into one of r conversation`s (like the other day i was talking about my phone and how i am getting sick of the touchscreen and he says something like "why don't you get a new one..i mean whats the point of having a phone you don`t like?"and i told him that's a good idea i might do that.) so i was wondering if tomorrow he say`s something like about the movie (like if it sounds like he wants to see it too) should i be like "hey do you want to come with us?" or would that be weird..Please help me give me any advice you have.(oh by the way im in 9th grade)
