A Quiet Place Part II Trailer

So I did not see the first "A Quiet Place" because I don't like scary movies, but I read enough about it to get the gist. So from what I can gather this trailer opens with footage that takes place before the first movie, kind of showing the arrival of the creatures from the first movie, then it jumps to scenes that take place after the first movie where a couple of new characters are introduced! The new characters are played by Cillian Murphy, who I've currently been watching in "Peaky Blinders", and Djimon Hounsou who has been in a ton of things but I recognize him most from his appearance in "Guardians of the Galaxy" and other Marvel movies. Seeing this trailer does make me want to go back and watch the first movie and then watch this one too when it comes out on March 20th!
