It could be nice if such a commercial would start with the actor or actress playing with the clickies together with their kids, thus providing proffesional voice acting for a clickie that matches a previous role of theirs.
Don't know if Gerard Butler has children or maybe nephews, but he could be great for a little ancient greece playmobil collection if they ever release that.
He wouldnt even need to say his famous lines from 300, wouldnt be appropriate for children. But providing a little speech for a playmobil captain to a bunch of hoplites could work. (with the children in the commercial providing a chanting "Wahoo!"response for the hoplites.)
And after that the children could be seen playing with the new toys while Gerard Butler talks about why he thinks playmobil is good for children.
Few shots of him since kids watching the commercial wouldnt care about that, but mostly hearing him speak while the kids play.
This is just an example of course, maybe Gerard Butler cares not at all for playmobil or might be very expensive, or there might never be a greek theme for playmobil.
