In some scary news, Emma Watson (best known as Hermione Granger in the “Harry Potter” series) came face-to-face with a stalker over the weekend who has bothered her before. Although unharmed, the actress was shaken by the encounter.

According to the UK Sun, she was filming her upcoming biblical epic “Noah” in Oyster Bay, Long Island when the unidentified man came up to her. Approaching the 22-year-old actress between takes, he tried to give her a letter, and Watson reacted by “scream[ing] with terror.”

Of course, Watson was scared by the incident, but it goes beyond that. As it turns out, she knew the man as someone who had attempted to contact her several times in the past. An official source from the film, which co-stars Russell Crowe and Anthony Hopkins, told Gossip Cop: “An unauthorized individual was removed from the ‘Noah’ production by on-set security, as he was found trespassing. No further action was required.”

Unfortunately, this is one of the downsides of fame. There are people out there that genuinely feel like the star in question knows them or is in love with them, or speaks to them in some way. It’s easy to say that the star overreacted, or that fans will be fans – but then again, nobody wants another Rebecca Schaeffer incident. The good news is that Emma’s security was on top of the ball, and kept her safe in the wake of this incident.

Set for release in 2014, “Noah” is directed by visionary filmmaker Darren Aronofsky. Known for getting powerful performances out of his actors with challenging subject material (“Requiem for a Dream,” “The Fountain”), a source said this Aronofsky tale is no different, and Watson is trying her best to hang tough: “It’s been a really tough shoot for her. The movie has been grueling anyway and this left a very sinister feeling hanging over the set.”
