Tuck Pendleton (Dennis Quaid) is an ace pilot who volunteers to be the first man to be miniaturized. He is shrunk but terrorists storm the lab to steal the technology.

Mr. Wormwood: You've got a great future in front of you in Retail Food marketing, and I just hate to see you throw it all away by going psycho on us.
Trivia: In the scene where Jack Putter's nightmare (about the overpriced items) becomes real while he's at work, a customer in line wearing glasses and a gray jacket says, "at $800 a bottle, who'd want to?". This was Chuck Jones. This is one of many references to "Looney Tunes"
Question: When Tuck is inside Jack he can't go through the heart - is this because Jack would have a heart attack or because Tuck would die?
Answer: I would say both probably.
Answer: Probably, but most likely it's because Jack's pod is fragile and wouldn't survive the shock wave heartbeats. The pod is experimental and built for scientific observation, not battle.
