Octavia Spencer is ready to rip up the rule book, blood-soaked knife in hand.
The actress and producer makes her lead debut in psychological horror film MA, opening in cinemas this weekend.
It sees her play Sue-Ann - a seemingly fun-loving veterinary assistant whose willingness to turn her basement into a teen party hotspot masks chilling intent.
It's a sharp departure from a run of roles that have made her an award season staple - from an Oscar-win for 2011's The Help, to nominations for Hidden Figures in 2016 and The Shape of Water a year later.
But the shift is purposeful. The three films, while making her one of only two black actresses to have received three Academy nominations, brought limitations.
"I felt people always wanted to see me as the nurturer, or the sage, or the sassy black woman. And the funny thing is none of them are real life.
"So I thought, well, since I'm not doing anything that remotely resembles me anyway, I may as well go for gold and just do something completely out of that range at the other end of the spectrum."
Spencer says she "leapt at the chance" to star in the film, drawn to the complexity of Sue-Ann, in a film that balances varying extremes of popcorn dark humour with claustrophobic terror.
Rebranding herself as "Ma" to a group of teenagers (fronted by Maggie, played by Glass actress Diana Silvers), she attempts to party "like a rockstar" - hard-drinking, kissing and dancing her way to approval.
Beneath this shock-value of watching Spencer in such unfamiliar territory, the antics of the character she plays reflects a lonely figure, traumatised by a moment in her past.
