CGI snakes are beheaded in slo-motion around 22 minutes in. It’s very clear it’s going to happen, so easy to look away.
Then, not long later, Milla Jovovich’s character is sleeping, Dave Bautista’s character wakes her up holding a knife above her, but then stabs a CGI scorpion with it. You don’t see the stabbing, but you do see it wriggling on the knife. It squeals in pain and he throws it, where the camera zooms in on it briefly.
