Target audince

My film is targeting teens and early adults. Due to this, I would want to advertise on Instagram and youtube as this is where most people in the age range of 18-25 are around. If possible, I would also try to get specific youtube and install famous people to promote the movie considering teenager s will listen to them. If for example, I could have a famous actor in an add say that he loves this movie or completely encourages people to watch it it will grow interested under the audience. The way that I find most of my movie is although though YouTubers who review them so I would contact certain youtubers to watch my movie and if they enjoy it to review it for some money of course,
