Skiathos was one of the major filming locations of Mamma Mia. It was in July 2008, when I was not there, so unfortunately, I missed Colin Firth, Meryll Streep and all the others of the cast running around the island and having dinner in the cool restaurants or hanging out on the port with that beautiful yacht they chartered for the move. The film is not exactly great, but the cinematography is amazing and truly shows the beautiful colours Skiathos has to offer. Our little video was made by a guest/journalist in part payment for a better booking deal. There are much better ones featuring Skiathos on YouTube
