Accused killer Jonathan Andrew Stenberg showed up on a film set in outback Queensland while on the run two weeks ago and auditioned for a role as a policeman in a serial killer thriller.

Mr Stenberg, wanted at the time over the decapitation of Edward "Ned" Kelly, 54, in NSW, answered an ad for a part in Mystery Road, a murder mystery film starring Hugo Weaving, Jack Thompson and True Blood star Ryan Kwanten.

Ironically, he won the role as an extra, playing a policeman.

Mark Ingram, the film's second assistant director, put posters up around Winton in central west Queensland two weeks ago asking for locals to audition as extras on June 23, two days after the decapitated body of Mr Kelly was found in his home in Broadwater, northern NSW.
