"People can expect the unexpected and expect to have a slapstick-oriented laugh," Mr Garman said of his five minute "kiwi western" Two Guns and a Funeral.
While last year's film was shot in Wanganui, this one was shot in a quarry down south.
"It's probably a feat in itself, shooting a desert western in Southland," he said.
Mr Garman said the fact his film was the only one set in the past set it apart from the competition.
"That adds production value straight away," he said.
Shot over the month's only two days of perfect weather, Mr Garman said filming wrapped on Sunday, and by Monday it was pouring outside.
Awards for the competition include best director, best actor/actress, best use of VFX, best animated film, and best Maori director.
Mr Garman was hoping for the big prize - best director - which came with a five night trip to Los Angeles to meet film and TV executives, sponsored by the Motion Picture Association and the New Zealand Screen Association.
