Mark Graham is New Zealand rugby league royalty, but to Luke Graham, he's dad.
The imposing back rower was named New Zealand Rugby League Player of the Century in 2006, and is still the only player in both the New Zealand and Australian league halls of fame.
A film and documentary maker, the younger Graham has now turned the camera on his father in the documentary 'Sharko', screening as part of the DocEdge film festival.
