NEW YORK — The stunt actor who fell 30 feet while playing Spider-Man on Broadway is walking again, and his father said Saturday that he can't wait to return to the role despite injuries that have him confined to the intensive care unit.

Christopher Tierney walked Friday for the first time since his fall during Dec. 20's performance of "Spider-Man: Turn Off the Dark" and is spending Christmas with his mother and brother in the hospital while recovering from back surgery, Tim Tierney said.

Julie Taymor, the director and co-writer of the $65 million production, visited the injured actor in the hospital on Christmas Eve, Tierney said. The show — the most expensive ever on Broadway — has been plagued by technical glitches, money woes and three other injuries, including a concussion and two broken wrists.

"They're eagerly awaiting his return," the actor's father said from his home in Portsmouth, N.H. "He just felt so blessed to be part of this whole creative process, and he just cannot wait to get back and perform in the show."

Tim Tierney said he believes his son will regain close to full mobility after recovering from a roster of injuries that included a hairline skull fracture, four broken ribs, a bruised lung, internal bleeding and cracks in three lumbar vertebrae.

Christopher Tierney will remain in the intensive care unit until at least today, then stay in New York City for rehabilitation.

As for when a return to the show might be possible, Tim Tierney said he was more positive than his son's doctors, who did not give a specific time frame for recovery.

"Doctors — they're always pessimistic," he said, adding that the pins and rods his son now has in his lower back will come out after he heals.
