David Fincher is back in his playpen, tinkering with all the dark and chilling elements that, let’s admit, are his specialty. There is the stylistic departure of Mank, a production Fincher was especially invested in because the screenplay was written by his late father. It was a comedy-drama and, along with The Curious Case of Benjamin Button, are the only Fincher features up to this point to not be of the horror and suspense genre. One might have consider it something of a biopic of Herman Mankiewicz, the writer of Citizen Kane. Even better, Fincher is back collaborating with Andrew Kevin Walker, who wrote Se7en. The Killer is much different however, thankfully. We do not need another Se7en.
