We’re holding off on posting anything that will spoil the plot but we will just highlight this from ‘Variety’ –
When asked why they cast Goode, Gillett and Bettinelli-Olpin alternate describing the actor as “imposing,” “beautiful” and “charismatic,” with a “gravitas” they knew the character needed to have the necessary impact for the ending. The actor shot on the final day of production, when the main set had already been caked in layers of blood, guts and viscera.
“He walked into this room covered in fucking blood and was like, ‘Okaaaaaay — so what am I doing?’” Bettinelli-Olpin says with a laugh. “We were like, ‘There is no ceiling. We will tell you if it’s too much. Let’s just take some swings here.’ Man, Matthew gave it a 100% for that day.”
“Melissa had kind of primed him,” Gillett says. “He had asked her, having read the script, ‘What is this fucking movie? What is the tone of this thing? What have I gotten myself into?’ And Melissa was like, ‘Don’t worry about it. Just do the weirdest, craziest thing that you can think of and they’ll love it and it’ll be great.’ And he did.”
