Don’t ask Dwayne “The Rock” Johnson for a photo. On Wednesday, the wrestler-turned-actor was approached by a security guard on a rooftop at 25th and Broadway on the set of his new flick, “The Other Guys,” co-starring Mark Wahlberg, Will Ferrell and Samuel L. Jackson. “The guard said he wanted to get a picture for his son, who was a huge fan,” says our witness. “But The Rock got all annoyed and said he can’t take pictures with everyone who asks. The best part is that when the guy said ‘Fine, but my son isn’t a fan anymore,’ The Rock gave him his trademark stare!” His rep didn’t return calls.
