I highly doubt it, every case I have ever heard of where something like this is an issue is a case where the person of resemblance is suing the company because it makes them look bad. The only case in which I imagine you’d get in trouble is if the actress’ family were to recognize this character’s resemblance, and were somehow able to legally represent this actress, which is highly unlikely considering the actress is not a minor, and has been dead for quite a while.
