Tatiana Siegel “The Flash” is almost here, and the rollout has been anything but typical. With just 13 days to go before the film’s June 16 release, titular star Ezra Miller has done no press and will make a low-profile appearance at the Los Angeles premiere on June 12, only posing for photos rather than doing interviews. The film’s director, Andy Muschietti, and cast members Ben Affleck, Sasha Calle and Michael Shannon, as well as fellow DC Universe superhero Jason Momoa, will also hit the red carpet that will be missing the standard press gauntlet. Typically, the star of a $190 million tentpole will promote the film in interviews across print, TV and oftentimes podcasts spanning multiple continents. (Harrison Ford has been ubiquitous in the run-up to the June 30 bow of “Indiana Jones and the Dial of Destiny,” including a high-profile showing at the Cannes Film Festival.)
