He said as a film maker he liked to see his movies played in cinemas, however changes with COVID-19 had made that more difficult.
"That's all sadly changing," he said.
"We were lucky Broke came out in 2016; it had its run in cinema.
"It's been on broadcast TV and SBS.

The addition to the streaming service also gives great exposure to Gladstone, which Mr Graham said was all part of filming there in the first place.
"I think Broke certainly highlights Gladstone as a character in the film," he said.
