The ad is one minute long, and the phone is on screen for exactly five seconds (and the first couple seconds, the phone is out of focus.) The ad is literally just RDJ standing in a bare studio, and the majority of the time, he talks about how the last HTC One won the best phone award at Mobile World Congress two years in a row. The best thing he says about the HTC One (M8) is that it is "somehow even better" than the old HTC One.
Yep, not kidding. That's the entire ad. This is what happens when you spend your entire marketing budget on the face and don't leave anything left over for the creative team. Still, the HTC One (M8) is a pretty awesome looking phone, so maybe customers will notice anyway.
