Is this guy interested in this case?

when we met for the first time, he smiled all the time and also laughed pretty hard at my jokes. also he mirrored my movements quite obviously, like holding glass to drink then putting down few times, then walking pace and other gestures lol. we watched movie and was like i lean to one side with my shoulder crossing leg he did the same later. so is this guy interested in this case as a friend or is it just normal?
