Initially, Magnús Scheving (a multi-awarded, skillful acrobat) performed all of Sportacus' various leaps & jumps himself, but when he tore a muscle while filming in summer of 2007, Disney executives immediately stepped in and insisted on bringing professional stunt men to perform some of the character's biggest stunts, or they'd pull the plug on the show altogether. Scheving claimed it was a minor mishap that only took him a few days to recover from and wanted to keep doing his thing as normal, but as he said during an interview "they're the ones with the money", so he gave in to prevent the show from being scrapped.
