The homages are obvious, especially regarding What Ever Happened to Baby Jane?, Magnolia, and The Shining.
Cregger has cited Paul Thomas Anderson’s Magnolia as an influence…
Inspired by John C. Reilly’s character in the similar ensemble epic Magnolia, Paul (Alden Ehrenreich) hides his demons in the most literal way…
…influenced by Paul Thomas Anderson’s Magnolia (1999)…
Cregger has stated that the work of Paul Thomas Anderson, especially Magnolia, was a huge influence on the film, and this is clear both in the multi-stranded narrative and some of the characterisation (Ehrenreich’s cop is very similar to John C Reilly’s character in the earlier film) and some kinetic camerawork that recalls the big dramatic moments in Anderson’s film.
The film follows a non-linear structure and has already drawn comparisons to Pulp Fiction or Magnolia, mostly because of the ensemble cast, and dark comedy, but that's where the similarities end.
