There's always one spoiler, isn't there?

Even after being "locked in a room" with the screenplay for three hours, Diane Lane, who is set to play Martha Kent in Zack Snyder's hush-hush 'Superman' reboot, let it slip to E! Online that the film's trajectory "does cover the entire range of years, from infancy on."

Doesn't she know that any and every detail is precious?

While some might argue that this detail doesn't, in fact, give too much away, we can now safely surmise that the new 'Superman: Man of Steel' film will be like 'The Curious Case of Benjamin Button' but told in reverse.

The new 'Superman' is set to open around Christmas 2012, unless this slip-up causes Zack Snyder to completely rethink the entire project.
