The studio quietly launched WB Archive Instant. According to the website, it enables subscribers who pay $9.99 a month opportunities to watch what the company calls “rare and hard-to-find” content. The moldy oldie movies include The Americanization Of Emily, A Face In The Crowd, Freebie And The Bean, and Black Legion. TV shows include The Adventures Of Superman, 77 Sunset Strip, and Cheyenne. New users can try the Warner Bros service two weeks for free. But for now it’s just available on PCs and Macs — no mobile devices — and televisions connected to a Roku box. Only the Roku can handle HD streams.
