You could split Robert De Niro's career into two halves, and how you perceive him will depend on your age. In the earlier part of his career, he was the Alpha-male tough guy star of 'Taxi Driver,' 'Raging Bull' and 'Goodfellas,' as well as the second 'Godfather' movie. To a younger audience, he's more recognizable as the cranky dad from 'Meet the Fockers.'
Between all the macho-man parts and the comedy though, he's found time to give a convincing and sensitive depiction of a gay man in 2007's 'Stardust' in which he played Captain Shakespeare. De Niro has been married to Grace Hightower since the 1990s, but in 'Stardust' he managed to see off the more obvious choice of British actor Stephen Fry for the part. Jack Nicholson was also under consideration at one point, but de Niro seemed right at home in the fantasy adventure.
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."
