Taiwan's struggling smartphone maker HTC is hoping Hollywood action-hero Robert Downey Jr can come to its rescue.
The star of the Iron Man franchise has reportedly been paid $US10 million ($A10.94 million) to feature in a TV commercial that will hit worldwide markets including the US, Britain and Germany on Thursday, HTC said.
The move sees the former smartphone powerhouse join fellow Taiwanese firm Acer in paying out big for Western celebrity endorsements as it struggles to turn around its fortunes in a market now dominated by Apple and Samsung.
A teaser ad titled "Big Things Ahead" released on video-sharing sites shows a man in a suit, thought to be Downey Jr, emerging from a military-looking helicopter carrying a briefcase before high-fiving another man carrying a phone. The clip ends with the acronym HTC spelt out as "Here's To Change".
Ben Ho, HTC chief marketing officer told reporters the campaign marks a shift in the company's strategy from promoting individual products to enhancing its global brand name.
