sorry if this has already been posted, but there is a great 9 minute video about the 20th anniversary week, it shows the Annalise documentary and a bit of the main episode it shows literally all the characters that are returning and all the ones that couldnt on the video, it almost brought a tear to my eye!!! anyway you need media player and i when you follow the link scroll down to the bottom and click the last one which says in brackets contains spoilers for uk. but its great great great!!
