At first, all I could find about the new cinema was this vague entry on the mall's website, which of course simply says it's "coming soon." But a representative of Westfield informed us that the theatre will have a soft opening "on Black Friday" - that's November 27 - followed by a full grand opening in December.
The Montgomery Royal will be operated by a local company (details on which we don't know, seeing as they don't even come up in a Google search), giving them major Local First Wheaton cred. They intend to show a "mix of first-run and indie films," making it sound like a less-pretentious Bethesda Row Cinema. The 'Royal will not, unfortunately, have a full-service restaurant and bar like the Drafthouse - which, sad as it may sound, will probably reduce their overhead costs by a lot, hopefully keeping them in business for much longer than two months.
