Actress Victoria Clark has joined the cast of The Happening. Our source is unsure of her role but says she has not filmed yet.

On IMDB.com someone posted this set report:
Was there all day today - they shot a traffic scene with a cop and a taxi driver (who actually looked a bit like a young Christopher Lloyd) at 18th and Rittenhouse Ave, a small backstreet behind the Square. I hung around and ended up as a background extra before being tossed because I had a crummy Phillies T-Shirt on. The people were cool, they figured I just got caught up in the mass of people - no security until M. Night showed up - set locked down then. They had a big crane shot and several POV shots on the Southeast corner of Rittenhouse Square. Very cool.
alright, i went down to smedley alley, a side street between 16th and 17th
on pine. saw shyamalan! no actors, although i probably couldve stuck around to
see them. i went around 9:30am. dont know how long filming will be going on
though.
I went down to the set today to the Kaiserman JCC.
They're not actually filming at the JCC, I guess it's just where the extras meet. But -
there were trailers, and food tents, and signs saying "TH," "Crew Parking,"
and stuff like that at the JCC. Where they were filming was in a neighborhood,
near 69th and City Line. There were a lot of roadblocks, and a lot of police cars.
There wasn't really much to see, except for the trailers that were there, and a bunch
of people walking around. You had to stay and watch behind the roadblock. The scene
they were doing was a Jeep, I think, that crashes into a tree. We waited quite a while,
and talked to various people. There were a bunch of different sets in that neighborhood.
Before we left, my mom talked to a guy that said that they were having camera problems,
and that they would be there, but he couldn't give her a definite time. They were
filming elsewhere, at 69th and City Line, where there were also roadblocks and police cars.
I highly doubt you'd see the actors, though.
