In this case, since the actor is the only one portraying the character (much like a Mr. Bean / Rowan Atkinson-type thing), the actor is permitted to be linked as well. Additionally, if the actor can be positively identified on a card, they can be linked (if they are the main focus of the card; for instance if the card is about "James Bond" and it's clear that the actor is Roger Moore, then he can also be linked).
