Blockbuster Inc. plans to offer movies that can be watched on Motorola Inc. cell phones. It marks the struggling rental company's first step into mobile video and is its latest effort at chasing down the customers that have abandoned its traditional video stores.

Blockbuster offered few details Tuesday on the plan, which expands on the company's OnDemand movie downloading service offered through set-top boxes for TVs.

It did not say when the phone service will be available or how much it will cost.

Kevin Lewis, Blockbuster's vice president for digital entertainment, said "thousands" of films will be available.

The company has been scrambling to find new revenue sources as traffic at movie rental stores wanes and customers move to online video and order-by-mail services like Netflix.

Blockbuster's alliance with Samsung Electronics America Inc., announced last month, will allow customers to rent movies with their remote control on Samsung's latest high-definition TVs. Earlier this year, Blockbuster introduced a similar on-demand service offered through TiVo Inc.'s digital video recorders.

On another flank, Blockbuster is promising 10,000 DVD rental kiosks to compete with Coinstar Inc. subsidiary Redbox, which is luring frugal customers with its $1-per-night DVD rentals.

Blockbuster joins a growing field of video services on cell phones.

Mobile customers can get clips on the mobile version of Google Inc.'s YouTube and movie rentals from Apple Inc.'s iTunes store on the iPhone. Verizon Wireless also offers V Cast, which shows sports, news and comedy clips on phones, starting at $15 per month.
