Zack Snyder Is Being Really Careful With His Man of Steel Script

As Michael Shannon hilariously recalled last weekend at the RiverRun Film Festival in Winston-Salem, NC, his meeting with Zack Snyder to discuss playing General Zod in Superman: Man of Steel was rife with cloak and dagger. "He's seriously sitting there, and he's telling me -- he's like, 'You can't read the script. So I'm just going to tell you what happens,'" Shannon said. "And he spent like a half-hour telling me every scene." Perhaps Snyder didn't think Shannon was as trustworthy as Diane Lane.

"I read the script," Lane -- who plays Martha Kent in the upcoming film -- told E!, "under lock and key. I was locked in a room with the script and was only allowed three hours with it. I nailed it into my memory. I'm really excited. I'm really not allowed to talk much about it, I think, but it does cover the entire range of years, from infancy on."

Sounds fun! For his next trick, Snyder will print all copies of the script with invisible ink that can only be read in black light. After that, carrier pigeon.
