"I feel for it because I wanted it to be true," a Twitter user wrote.
Matafeo later clarified that she was definitely joking: "If I have to explain that I'm not actually in Knives Out 2, I'm gonna have to get my Knives Out 2 stab myself in the thigh — u feel me???"
While she may have fooled some fans, Matafeo's rom-com series Starstruck is experiencing critical acclaim both here and abroad. The series is a BBC and HBO Max co-production and streams in New Zealand on TVNZ OnDemand.
The sequel to Johnson's whodunit mystery is expected to be released in 2022, and while Matafeo may not be starring, there is still plenty to be excited about.
Daniel Craig is reprising his role as detective Benoit Blanc, alongside a new ensemble of stars.
Kathyrn Hahn, Dave Bautista, Janelle Monáe and Kate Hudson are among the actors cast in the upcoming film.
Collider reports the movie has begun filming in Greece, and Johnson shared a photo on Twitter yesterday announcing production was under way.
The first instalment was a huge commercial hit. It grossed US$311 million worldwide at the box office with a US$40 million budget.
The upcoming movie will screen on streaming giant Netflix, after the platform purchased Knives Out 2 and Knives Out 3 for a staggering US$450 million.
