Louis Lane wasn't the most boosomy of a character anyways so that won't really be necessary. It worked for Kate Bosworth, look-wise. Now if they were looking for Power Girl, then they need someone "busty". Speaking of Power Girl, maybe their looking for Power Girl for this movie? Alice Eve would make a good Power Girl. Maybe their looking for Lana Lang for this film, the character became really famous with the Smallville show and I can see Diane Kruger as a good Lana Lang.
