Local filmmaker Stephanie Saint Sanchez once told us that one reason she liked the short film format was if the film was bad, you didn’t have to wait too long for it to be over, and if it was good, you could watch it again right away. If experience is any guide, the films screened at the Aurora Picture Show’s Extremely Shorts Festival are all going to be worth repeating. Austin’s Zellner Brothers have been tapped as judges for this year’s competition. The filmmaking duo will select from 20 to 25 short films, each under three minutes long. Topics range from silly to serious and formats include comedies, dramas and fantasies. There are two screenings on Friday and another one on Saturday. At Saturday’s screening, Audience Choice awards will be handed out (along with cash prizes).
