The above video shows that even if you are an enormously popular, successful and award winning actor, that doesn't necessarily mean everything you do will turn out well. In fact, sometimes the best performers can still turn in "cringeworthy" performances. Of course, sometimes the actor is limited by a bad script or bad director, but that may not be the case here.
In the above example, Robert Downey Jr. is back with another HTC ad. It actually seems like it was mostly improved from a loose script. It also looks like they probably did several takes to try and get it right, but eventually just gave up and called it a day. If this is HTC's way of getting their money's worth out of RDJ, then they need to hire better writers and come up with much better ideas than this.
