John Leguizamo experiences The Happening

And Spencer Breslin signs up too…

When M Night Shyamalan sends Mark Wahlberg on the run from eco-terror this September, he’ll at least have a best friend to help with his family, as John Leguizamo has signed on to co-star in the movie, alongside Wahlberg and Zooey Deschanel.

And Wahlberg’s immediate movie family is getting bigger too, with Spencer Breslin joining the cast as his son. Of course, he has an in with the director, since his sister Abigail starred in Signs. But even with direct access to Shyamalan, he hasn’t been told much about the script, claiming to have only read an old draft. But according to him, his character is "a typical teenage boy, a bit of a smartass."

He’ll need all those smarts when the world tries to kill him…
