Who Knew? With Marshall Brain

Back to the main review

What’s the Story?

WHO KNEW? WITH MARSHALL BRAIN takes viewers on behind-the-scenes tours of some of America's most impressive factories. In each episode, host Marshall Brain investigates three cutting-edge manufacturing processes, getting hands-on with the engineers and laborers who create a spectrum of items -- from high-performance racing bikes to everyday American currency. Along the way, he explores how technology has changed the manufacturing process and allowed these factories to ensure their products' perfection.

Is It Any Good?

The show has a lot in common with its many peers (including How It's Made and John Ratzenberger's Made in America), but it's certainly a worthwhile viewing choice if you're the type who's intrigued by the ins and outs of the production process. The series also spotlights the craftsmanship that's often overlooked in the technology era and gives credit to the workers whose skills still make them irreplaceable by machines.

And for the mechanically unsavvy, the good news is that Brain's background in both science and communication makes him an adept tour guide; he easily tweaks the experts' technical jargon into a narrative that any viewer can easily understand. The subject matter probably won't interest young kids, but if your tweens and teens will tune in with you, you'll all come away from the show with a better understanding of what's involved in making some of the products we often take for granted.
