Daniel Maurer Baldwin leaves the building.

Displaced NYU students got an unexpected dinner guest today, as Alec Baldwin made a star appearance at the school’s student center.

The “30 Rock” star stopped into Kimmel Center, off of Washington Square Park, around 7 p.m. tonight. “I’m an alum and John Sexton asked me to come and talk to the students, thank them for their patience,” he told The Local as he left the building, politely breaking free from a dozen students that swarmed him at the elevator.

NYU relocated about 6,000 students earlier today after back-up power ran out at their dorms, according to an e-mail from Jules Martin, the school’s Vice President for Global Security and Crisis Management. Around midday, the generator at 3rd North residence ran out of fuel, creating a “temporary smoke condition,” but power was expected to be restored this evening, the e-mail said. Displaced students are currently showering at the school’s two sports complexes.

Mr. Baldwin, who lives near Kimmel on East 10th Street, has also been displaced by the storm: he told The Local that he and his wife had moved to a friend’s hotel because his elevator was out and taking their two dogs up and down several flights of stairs “wasn’t working.” He was also out of work for two days: “the show I do,” he said, referring modestly to “30 Rock,” suspended filming on Monday and Tuesday because team members couldn’t make it to Silvercup Studios in Queens.

As soon as Mr. Baldwin made his appearance alongside school president John Sexton in the cafeteria, students charging their phones, pecking at laptops, and dining at Kimmel sent out word via Twitter.

“Alec Baldwin just came to Kimmel and told us to stay safe #YesSir,” wrote @Glenneth_Coco.
