While I wouldn't want them to replace Brandon Routh, I'd be fine with bringing someone else to play Lois. Nothing against Kate Bosworth as an actress per se, but Lois should be a little more fiery, and Bosworth came off much too blandly (though that could be down to her director as well). I'd prefer somebody like Anne Hathaway or Rachel McAdams.
I think that if they do
recast either Superman or Lois, they should go with someone not previously associated with the characters from any other version of Superman
- in other words, no Erica Durance or Tom Welling, for example. While I like both actors and their portrayals of the roles, if you're not literally doing Smallville: The Movie
, it would just be too weird to have one of them show up, especially if it was
only one of them.
