U.S. film studio Warner Brothers is offering five additional movies for rent on social networking website Facebook, a further sign of intensifying competition in renting out movies on the Internet.

Warner Bros, a unit of Time Warner Inc, would offer films such as "Harry Potter and the Sorcerer's Stone," "Harry Potter and the Chamber of Secrets," "Inception," "Life as We Know It" and "Yogi Bear."

Earlier this month, Warner Bros had told media that it would make some of its movies available on Facebook, where consumers can pay the rent using Facebook Credits, a virtual currency so far used mainly in social games on the site.
