US indie rockers The Postal Service may deliver a stiff letter to Apple over its new Intel TV ad.

As originally noted by Wired's 'Cult of Mac' on January 11, the ad is uncannily similar to the band's own promotional video for the band's song, 'Such Great Heights'. The song is available for sale from iTunes.

Apple's ad spot features a white-suited technician in the clean room of a processor production fab. The Postal Service's video also features a white-suited technician in the clean room of a processor production fab.

The band claim the composition and elements used in both ads are similar - and ignorance is no excuse: both films were made by the same movie makers, Josh Melnick and Xander Charity, whose working name is Josh & Xander.

Band member Ben Gibbard's annoyed: "It has recently come to our attention that Apple's new television commercial for the Intel chip features a shot-for-shot recreation of our video for 'Such Great Heights' made by the same filmmakers responsible for the original," he wrote online.

"We did not approve this commercialisation and are extremely disappointed with both parties that this was executed without our consultation or consent," he thundered.

Apple fell into controversy recently over its Eminem iPod ad spot, which seemed uncannily similar to a previous ad from Lugz footwear.

Indeed, the name of the company, 'Apple', is also controversial, with The Beatles' holding company, Apple Corps, currently taking Apple through the courts because of the computer company's move into music.
