Gnarls Barkley video fails epileptic test

Gnarls Barkley's new video has been banned from US TV after failing the Harding Test, which monitors strobe effects that trigger epileptic seizures.

The promo for 'Run', which features a cameo from Justin Timberlake, will only be available online until director Happy can make changes that meet guidelines established to prevent TV images from disturbing epileptic viewers.
