The actor, who suffered a skull fracture and cracked vertebrae, among other injuries, said, "I feel great, the fresh air. I can't wait to actually take a walk around New York, and maybe even be on the West Side of the city. I feel like I've been here forever...I'm going to drop my stuff off at my house and maybe go do some belated Christmas shopping."
Tierney entered the Rusk Institute following a stay at Bellevue Hospital, where he underwent back surgery.
Tierney also recently spoke with WCBS-TV's Dana Tyler about his injuries and recovery as well as his desire to return to the production.
The accident at the Foxwoods Theatre, Tierney told the television reporter, "was just, you know, a bit of human error. I'm supposed to jump off the bridge... And I was tethered to my back, but it just didn't get tethered to the stage. So when I went out, as I do with everything, I just go for it, [but] there was no pulling myself back.
"I was falling," he continued, "and then I saw, once I hit the darkness of the stage, I had to just turn it real quick so I wasn't going to fall on my head. And I crashed on my back. The last thing I remembered was just going, 'Oh, God!' [Laughs.] And that's it. Then I kind of passed out."
Tierney, who was making his Broadway debut in the Julie Taymor-directed production, said he "broke four ribs, I broke three vertebrae. Fractured my scapula, fractured my elbow, and I fractured the back of my head." The dancer, however, bears no ill will against anyone involved in the accident. "They came and visited [me in the hospital], and [it's] completely water under the bridge and forgiven and forgotten," he said.
In fact, Tierney added, "I'm glad to be working on the show. Not glad, overjoyed to be working on the show...I'm meant to be Spider Man."
Tierney, who explained that the "immediate outpouring of love that happened [following the accident] is so unbelievable," said he can't wait to return to the Broadway production, although he realizes his recovery will take months.
"I'll come out and I'll swing around and then I land on the balcony! I'll look around and there'll be, like, five or six kids right there. And it's a mixture of abject fear and admiration," Tierney recalled about his brief run in the musical. "They scream, and I can't wait to make them scream [again]."
Spider-Man will officially open on Broadway Feb. 7.
