As we get closer to the release of Man of Steel, we've seen a shift in the promo. It now seems to be focused on the emotional side of Superman, specifically the link to his two dads (see latest spot). This article below is from this week's Entertainment Weekly.
The film opens on Father's Day weekend, and Sears is also focusing on the father/son connection in its latest Man of Steel ad.
So bring some Kleenex, because it looks like you're gonna need them when Man of Steel opens June 14.
