In our humble opinion, Powershop’s ‘Same Power, Different Attitude’ campaign is one of the best campaigns of the year. But we wondered aloud a couple of weeks ago whether its latest execution featuring Darth Vader prancing through a field like Julie Andrews crossed the IP line. Turns out it did, and the LucasFilm patent lawyers have been in touch telling them to cease and desist. They’ve done as asked, but, with a dose of challenger brand cheek, they’ve also taken a leaf out of 42 Below’s book and, with the help of its PR agency Sputnik, decided to have a bit of fun with the apology letter.
