With director Zack Snyder's Man of Steel opening today nationwide (many theaters had screenings as early as 12:01 a.m.), it's impossible to swing a dead Kent without hitting a dozen Superman-related items online or in print. Although most of them are directly related to the Warner Bros. franchise reboot, there are plenty with clear comic-book ties. Here are just a handful of them:

• Superman gets the cover of this week's Entertainment Weekly, on which Neal Adams and Murphy Anderson's rendition of the Last Son of Krypton (from December 1972's Action Comics #419) is given prominence over the movie and TV versions -- possibly because Man of Steel star Henry Cavill was featured in April, but hey, we'll take it. But poor, poor Brandon Routh ...

• Mark Waid, whose 2003-2004 miniseries Superman: Birthright (with Leinil Francis Yu) influenced Man of Steel, saw the movie last night and tweeted, "That thunder you heard at around 9:15 EST was the sound of my heart breaking in two." He followed that with a review on his Thrillbent website that he prefaced with, "It’s a good science-fiction movie, but it’s very cold. It’s not a very satisfying super-hero movie. That said, if your favorite part of SUPERMAN: THE MOVIE was Superman standing in the Fortress while Jor-El lectured him, you’re gonna love MAN OF STEEL."

• USA Today's Brian Truitt examines "Why Superman is the greatest American hero" in an article that includes quotes from Waid, Scott Snyder, Brad Meltzer and Jim Lee. There's also a timeline tracing the evolution of Superman's S emblem.

• The Kansas City Star tries to figure out where exactly Smallville is.
