I love receiving snail mail from festivals around the globe, indeed, especially if a film of mine is screening and they send me a program. I also like snail mail updates on upcoming festival call-outs like the one I received the other day from the Croation One Minute Film Festival, now in its eighteenth year.
The festival takes place in Požega from May 27 - 29th, 2010. Deadline for entries is April 9th and the top prize is 1000 euros.
It is important you read the regulations and the online entry form can be found here.
