Portugal has held its first-ever film festival featuring short movies made with mobile telephones, which are growing more and more popular around the world. More than 30 international films ranging in length from 30 seconds to 10 minutes were shown on a normal screen along with regular movies as part of the three-day "Olhares" festival which wrapped up Sunday. Organizers of the fourth annual event said they decided to make room for movies filmed with camera-equipped mobiles, dubbed "pocket films," this year to showcase the emerging form and consider what effect it may have on cinema.
