Filmmaker Luke Graham didn't have to look far for the subject of his latest documentary.
He's turned his lens on his father: Kiwi rugby league legend Mark Graham.
Mark's outstanding playing career included 29 tests for the Kiwis between 1977 and 1988...including 18 as captain.
He also made 150 appearances for North Sydney and was the Dally M second rower of the year in 1981 and 1982.
He was the first Kiwi inducted into the NRL Hall of Fame and in 2007 was named New Zealand Player of the Century.
Luke's documentary on his dad is called Sharko - which debuted in New Zealand as part of the DocEdge film festival and is out in cinemas around the country next week.
The project is a personal one for both father and son - the film also details a family tragedy and the mental toll that it took.
