Paths of Glory

Not a terrible movie by any means but Doctor Sleep. Poor elderly folks just weren’t prepared for certain events

Some other parallels I haven’t seen mentioned could be the revelation that the Baron is Jessica’s biological father, Chani dying while giving birth to twins, Alia being Paul’s secret sister.

Star Wars being a rip-off is a bit harsh and undeserved but I’d definitely say there was influence from Dune.
