Returning Actors

I am watching Smallville Season 7 too quickly to post about individual episodes. It becomes evident that we have seen certain actors before:

two previous Superman actors play new characters, one a mentor to Clark, the other a villain;

the actor who played Lana Lang in a Christopher Reeve film plays Martha Kent;

the actor who played Wonder Woman on TV plays Chloe Sullivan's mother;

the actor who played Supergirl in a feature film plays Lara and later played Supergirl's step-mother on TV;

I have been told that the actor who played a dying elderly woman conned by Lex Luthor at the beginning of Superman Returns had played Lana Lang in the 1950s;

I think I have missed one.
