In production for over four years, Lucas Martell’s six-minute animated short Pigeon: Impossible has finally been posted to YouTube in its high definition entirety. Since May 2008, Martell has been posting monthly podcasts on the making of his film – about a “rookie secret agent faced with a problem seldom covered in basic training: what to do when a curious pigeon gets trapped inside your multimillion dollar, government-issued nuclear briefcase” – on his own channel, and now the very polished end result, complete with a Giacchino-styled musical score performed by a live orchestra, can be viewed in 360p, 480p or 720p HD alongside all 19 installments of his behind the scenes podcast.
