T-mobile 'Katy's project: pop video' by Saatchi & Saatchi

T-Mobile is launching a new European campaign in collaboration with Katy Perry.

T-Mobile is giving fans the chance to appear in the popstar's ‘Firework’ video to be filmed at the end of September. 

A TV ad to air in six European markets, exclusing the UK, features Katy Perry asking for fans to join her in her video.  Other features of the campaign will include in-store promotions and print elements.
