Warner Archive Instant features films including Laurel and Hardy's "Bonnie Scotland," the 1960s comedy "Where the Boys Are," the 1959 horror classic "The Mummy" and television's 1950s series "The Adventures of Superman."
The service, which is priced at $10 a month after a free trial, allows consumers to watch on a computer or via the Roku streaming television box.
"There will be more of everything as we're trying to strike a balance," the company said in a tweet. "Stay tuned and join when you like the programming."
The service is only offered in the United States for now, Warner said.
