transformed from dreamboat to daredevil when he scaled the Empire State Building.Well, at least 18 floors of it.The Oscar-winning actor’s career reached new heights at the New York landmark as he pulled off the awe-inspiring stunt to announce his band Thirty Seconds to Mars’ upcoming “Seasons” world tour.Their fearless frontman said of his Empire State stunt, “The building is a testament of all the things that can be done in the world if we put our minds to it, which is largely the inspiration behind our most recent album, ‘It’s the End of the World but It’s a Beautiful Day.’ ”Leto — who is the first person to ever legally climb to the top of the Empire State Building, according to building officials — scaled from floors 86 to 104 on the east side of the landmark. His 20-minute hike took the “Dallas Buyers Club” actor some 1,300 feet up in the sky.After a performance at the top of the Empire State Building, Leto spoke about his bucket-list adventure on the “Today” show.“I was more excited than nervous, to tell you the truth,” he said.
