(AP Photo/OnLocationVacations.com, John Matthews) (Newser) – Spider-Man's back on his feet again: The stunt double who fell 30 feet into a stage pit during the Broadway musical walked for the first time yesterday following back surgery, his father tells the AP. Christopher Tierney is expected to regain full mobility despite the fall that caused a hairline skull fracture, cracked ribs and vertebrae, and a bruised lung. Tierney's plunge was only the biggest in a string of problems for the $65 million show, the most expensive in Broadway history. It's still in previews and will have its official opening next month.
