Australia's first Muslim romantic comedy could prompt more people from minority groups to share their stories through film, its creator says.

Ali's Wedding is based on the true story of writer Osamah Sami, who also plays Ali, the Melbourne-based son of a Muslim cleric who tells a lie that sets off a cringe-worthy chain of events.

The wedding in question is Ali's arranged marriage, which he accidentally agrees to at a tea ceremony but which lasts less than two hours.

Osamah says it's hard to describe how it feels to see his life on the screen but he's eager to see how others respond.
