Look, I think the rake promotion is a poor choice, and the parks are definitely a better brand to market. This came across to me as a shareholder presentation for the new buyers than something to encourage people to come back to the parks - BUT - Putting Clark at the front of the campaign is probably the best part of that ad. Sure, Average Joe doesn't know who he is, but if they persist with this marketing strategy (remember, he's fronted the media recently for soundbytes instead of Bikash) he starts to become the human face of the company, which is a far better image than a faceless rake. (I also don't think it's Clark who does the voiceover).
The Kirby name founded Movie World and the Village company, and while definitely not of the same calibre, has hints of the days where Roy Disney fronted the cameras on behalf of the Disney company. By all accounts Clark will continue to lead in some capacity with any new owner, and marketing him now (albeit probably a bit later than it should have been) is a great step at showing that it's "business as usual" when the new owners come on board. No doubt the company will take a direction that is different to what we have come to expect from Village (one can hope!) but having Clark at the helm, AND as the face is the kind of thing Eisner did when he rose to the top at Disney.
While my personal opinion of Clark isn't that high (an impression taken mostly from his posted antics on social media), it isn't horrible. I'm sure others would hold a negative opinion of him for different (and probably better positioned) reasons than mine - but as you say - quite a lot of people don't know who he is - but perhaps this is the start of Clark's "face of the company" debut, with more to come. If i'm wrong about that, then I wholeheartedly agree, its a poor choice for him to face the campaign, but if i'm right, its a great foundation for them to build him a public image that would well suit a family suite of theme parks.
