Calling all smartphone filmmakers: the Mobile Film Festival in Paris, presented by BNP Paribas in partnership with the UN, is seeking one-minute-long films shot on phones for its 2015 edition with the theme of Act on Climate Change. Flex your small-scale production skills on an international stage, help get the word out about climate research and activism, and you might just win a budget of 30,000 euros (approx. $34,000) for your next project. With major festival selections shot entirely on phones, 2015 will likely go down as the year when mobile filmmaking came into its own — be part of that vanguard and inspire environmental action. The submission window stays open until September 28th.
