The idea of a 48-hour film competition wasn't new when, 14 years ago, organizers decided Boise should give it a try and launched i48. Each June, teams write, cast, shoot, score and edit original short comedies, dramas and sci-fi short subjects in a 48-hour frenzy. Prizes and trophies are offered, but the real thrill is sharing films with friends and family on the big screen at The Flicks and The Egyptian. I48 has become so successful over the years that it spawned h-48, a horror-themed competition each October, and the i48 February challenge, which made its debut earlier this year. Soon, maybe the 48 won't only stand for how many hours filmmakers have, but also how many related events there are.
