Tom, who plays Draco Malfoy in the wizard film series, delivered the free pizza to film fans who had been gathering outside Manhattan's Lincoln Center yesterday to show his appreciation for their years of support.
Felton wrote on Twitter today: 'I enjoyed my role as pizza delivery boy last night!'
The 23-year-old was forced to leave before he finished distributing all the pizza, and he later apologised to all the fans he missed.
He added: 'Hope everyone who camped out is ok! Sorry I couldn't get pizzas to all of you I was getting told to leave!'
