He has a role in Stray, the debut feature film written and directed by Dustin Feneley, of Auckland.
It had been two years since Sean's scenes were shot, prompting him to look twice when he saw himself on screen.
''I said: 'Woah, is that me?' cause I was really small then and really young.''
Sean had drama behind the scenes as well, when on the last day of his filming he was rushed to Dunedin Hospital.
Sean has hydrocephalus. Fluid builds up in his skull and causes the brain to swell. Two shunts at the back of his head help drain the fluid.
''It's got two tubes attached, and it drains bad fluid down into my tummy. If bad fluid comes up I get really bad headaches.''
When he developed headaches on the film set an ambulance took him to Dunedin Hospital, but he recovered well and was more interested in his next challenge of being in another movie one day.
The experience had ignited his interest in acting, and he was looking forward to friends and family seeing the movie.
''I would love to be in another movie, because I will be more famous,'' Sean said.
