One movie executive meets another at a news conference.
"Hi Harry. What've you been doing lately?"
"I'm making a new movie. It's all about a runaway locomotive."
"Yeah, and it's really character-driven; not just special effects."
"Yep. There's a 'Huckleberry Finn' and a 'Becky Thatcher' and a 'Tom Sawyer' in it."
"Well, gee, Harry. I don't think it'll work."
"It's too, too Twain."
