I've never 'got'

I don't get badly dubbed beauty product TV adverts. The actors speak out of synch, because that's not their voice. All this overdubbing. Generally it's hair products. They're hired for their 30 second 'acting ability', but not entrusted to speak with their own voices. I don't get that. I like to see the mouth movements match the words, in time.

they are foreign adverts redubbed for broadcast different countries.

makes sense now, eh?
