Why don't you have "FOLLOW" button?
It would be great if you put "follow" button on actors/actresses, directors and movies pages so we could be able to hear upcoming news about them. It could show up on our profile pages like there are two new messages such as Johnny Depp announced for a new movie or the new trailer of Black Mirrors' new episode has been realesed etc. Under recent circumstances we always have to visit their pages to learn if there is something new or not. You can develop this kinda feature, can't you?
