During filming, David Morse (Mr. Turner) did not speak to Shia LaBeouf (Kale) or any of the other teens. LaBeouf said, "When we finished filming, he was very friendly. But he's a method actor, and as long as we were shooting, he wouldn't say a word to us."

While David Morse (Mr. Turner) was filming a scene with Shia LaBeouf (Kale), he slammed his hand into a wall, breaking three fingers. LaBeouf said, "You could see that they were broken. They were all mangled. But he didn't say a word about it. Everybody's asking him what they can do to help, and he just says, 'I'm okay. I'm okay. Let's go again.' It was intimidating, to say the least."

The script was written in the 1990's and was optioned. The original studio let the option expire after hearing about Christopher Reeves' Rear Window remake. It wasn't till 2004 that script was rewritten and sold.
