HER mum, Yvonne Keating, is thrilled at the news that the film has been selected to feature at the Tribeca Film Festival in New York in April.
Missy (12) has already been tipped for big things for her starring role in horror flick Dark Touch.
"Wow... Dark Touch the movie Missy starred has been selected to screen at the Tribeca film festival," Yvonne posted on Twitter.
After people congratulated her on her daughter's success, Yvonne added that Missy was "thrilled", describing the process as "very exciting".
'Dark Touch tells the story of an isolated house in the countryside which appears to come alive and attack the family living inside it.
Missy plays Niamh, the sole survivor of this carnage, after the house has killed her parents and little brother.
The youngster has come a long way since making her acting debut alongside her parents Yvonne and Boyzone singer Ronan for a Nintendo DS television advert that was released in Ireland in 2009.
Dark Touch is just one of four Irish films selected for the Tribeca Film Festival. The world premiere of the Irish feature film Run And Jump, directed by Academy Award- nominated Steph Green (New Boy) will take place at Robert De Niro's Tribeca Film Festival next month.
Neil Jordan's Byzantium and the US premiere of Lenny Abrahamson's What Richard Did will also feature.
What Richard Did cleaned up at last month's IFTAs and has made a household name of Jack Reynor, who will star in Michael Bay's latest offering of blockbuster Transformers.
Both Run and Jump and What Richard Did will screen with 20 other international features and documentaries in the Viewpoints section of the Tribeca festival which focuses on stories told from distinctly male and female perspectives.
Neil Jordan's Byzantium stars Oscar-nominated actress and Carlow native Saoirse Ronan. It will screen along with films from well know filmmakers including Mira Nair, David Gordon Green, and Neil LaBute in the Spotlight section.
The Tribeca Film Festival will take place in New York from April 17-28.
It was started in 2002 by Jane Rosenthal, Robert De Niro and Craig Hatkoff in response to the September 11, 2001, attacks on the World Trade Center and has become one of the most important festivals on the international calendar.
