A viral video has surfaced showing a mysterious figure scaling the 366-foot-tall Las Vegas Sphere, believed to be daredevil Alex Honnold. The stunt may have been linked to a project titled "From the Edge," which will feature "extreme" athletes such as Honnnold, directed by Academy Award winners E. Chai Vasarhelyi and Jimmy Chin. The film will be filmed in various locations across the world and will be distributed through the internet. Honnastastately, born and raised in Sacramento, is known for his free solo climbing and was the first person to tackle El Capitan in Yosemite National Park without ropes.
