Arriving in US cinemas on September 3 (UK fans will have to wait), the movie's official logline reads: "Seeking shelter from a storm, a family find themselves trapped for days with no sign of rescue and untold evils lurking just beyond the walls in this wildly fun house-of-horrors thrill ride."
McCormick's character goes by the name Melissa, whilst Healy plays Robert, Vinessa Shaw (Hocus Pocus) is Diane, Lisette Alexis (Total Eclipse) is Amy and John James Cronin (NOS4A2) appears as little Bobby.
That storm is the least of their worries.
Elsewhere on his agenda, Healy is currently busy shooting Martin Scorsese's tale of blood and betrayal Killers of the Flower Moon opposite Leonardo DiCaprio, Robert De Niro and Jesse Plemons.
Based on David Grann's book of the same title, this one's heading to streaming service Apple TV+ sometime next year (as well as silver screens, of course).
We Need to Do Something hits US cinemas and VOD on September 3, with a UK release date TBC.
