Denis Villeneuve revealed that he bans the use of cellphones on the sets of his movies, just like Christopher Nolan. Villeneuve and Nolan are two of the most critically acclaimed filmmakers of the 21st century. In some ways, Villeneuve and Nolan are very similar filmmakers since their movies tend to be very epic in scope. Denis Villeneuve’s best movies include Prisoners, Sicario, Arrival, Blade Runner 2049, and both of his Dune films. The exceptional ratings that all these movies have achieved are a result of complete dedication from Villeneuve and his entire crew.
