Jonah Hill had the world at his feet as a comedy actor, but made the brave step of drastically changing his appearance when he decided he wanted to take on more serious roles. He had us all rolling in the aisles in 'Superbad' and 'Knocked Up,' and turned in a truly memorable performance as Leonardo DiCaprio's sidekick in 'The Wolf of Wall Street.' Hill was so keen to land that role that he worked for less than a tenth of his usual rate just so he could take the part. That shows you how serious he is about his craft - as does his dramatic weight loss.
If you go back five or six years, Hill was roughly twice the weight he is now. He looks happier and healthier - but shrinking down so much has drawn attention to the fact that he's a lot shorter than people who saw 'Superbad' must have thought. Hill is 5 foot 7. He may have lost a lot of size, but he hasn't lost any of his on-screen presence! He credits acting buddy Channing Tatum with helping him to get into shape.
When we think of inventors, the image that comes to mind is usually that of a frazzled scientist toiling away in a lab, not celebrities pulled from the pages of Us Weekly. However, a number of well-known public figures hold patents for various innovations. Some are related to the work that made them famous, while others are offshoots of hobbies or just a single great idea.
Part of guitar wizard Eddie Van Halen's signature sound was his two-handed tapping technique, but letting all ten fingers fly while simultaneously holding up the guitar's neck could get a bit tricky. Van Halen came up with a novel way to get around this problem, though; he invented a support (top) that could flip out of the back of his axe's body to raise and stabilize the fretboard so he could tap out searing songs like "Eruption." While Van Halen was obviously interested in improving his guitar work, the patent application he filed in 1985 notes that the device would work with any stringed instrument.

It’s probably not surprising that James Cameron—who designed a submersible to take him to the deepest known part of the ocean—will often invent technology to make his films if what he needs doesn’t exist. He holds a number of patents, including US Patent No. 4996938, “apparatus for propelling a user in an underwater environment,” that he and his brother, Michael, created to film The Abyss and patented in 1989. The device is basically an underwater dolly equipped with propellers that makes it easy for a camera operator to maneuver in the water—and allowed Cameron to capture the shots he wanted for the 1989 film, part of which was filmed in an abandoned nuclear reactor.
In 1987 Jamie Lee Curtis designed and patented a disposable diaper that included a waterproof pocket that held baby wipes. She hasn't profited from her idea yet, though, since she refuses to license the patent until diaper companies make biodegradable products.
You know him as a rock legend, but Neil Young also loves trains—so much that he owns a stake in a model train manufacturing company and has an extensive collection. He also holds seven patents related to model trains, including Patent No. US5441223, "Model train controller using electromagnetic field between track and ground."
