Hey, wanna be an extra in something Greg Grunberg is shooting tonight?

I have no idea what Heroes star Greg Grunberg is filming tonight, but he needs extras for it.

Grunberg says on Twitter that he needs extras from something he is filming tonight. You need to be 50 years old or older (he says you can bring your parents or grandparents), and it will take an hour or so. By the way, this is in Santa Monica. If you fit the bill and you're interested, call the Hotline: 323-936-4943.

I assume this isn't for Heroes since NBC would probably need to coordinate it.
