The 38-year-old actor, who plays Batman in the latest installment of the Caped Crusader franchise, spent more than an hour shaking hands with fans and signing autographs on the red carpet at the event in Leicester Square, reported Sun online.
Despite happily interacting with the crowd, the British actor was spotted applying hand sanitiser into his palms as soon as he left the venue to get into his chauffeur-driven car.
The photographer, who took the picture said, "It was priceless. He's a fearless crime-fighter in the film but in real life signing a few autographs was a gamble he wasn't willing to take without some chemical protection afterwards."
