I'm really digging the "arch-rivals" Superman Returns DVD commercial, the one that focuses on Superman and Lex exclusively.
Looking back on the movie now, it's now a love/hate thing for me regarding how little screen time Supes and Lex had together. Most of the movie they each had their own storylines until they finally met again on the new island. Hate because there's so little screen time of interaction, but love how it only just makes that new island scene so much more pivotal.
