Wasn't it just last year that TJ Miller was treading the boards at iO and Second City and hanging out in dank Chicago watering holes sharpening his stand-up? Yes. All the more amazing then, that now he's big stuff...and getting bigger.Thanks to Katie Moore for the screengrab of T.J. Miller hitting the airwaves to plug his big-screen debut in the monster smash Cloverfield.

Here he is in New York Magazine, where he explains that at least of few of his funniest lines in the movie were, indeed, improvised: "I had some great lines to work with, but I improvised a lot on set. My character’s awkward; he’s the friend that everyone loves but finds kind of annoying. My thought process was, everyone’s going to react to this incident differently and my character would react in a funny, believable way. They really let me run with that. I was lucky."

Discussions have exploded on the Chichahahago message board with critiques of the movie, and that's also where Miller has confirmed: "Gentlemen, and ladies, I will be a guest on the Late Show with David Letterman, Thursday, January 24, 2008. This will be my first, and if it does not go well possibly last appearance on National Television as myself. Please tune in, and critique vigorously."

Oh, and there's going to be a sequel. Cloverfield II: Electric Boogaloo, or something like that. "What’s certain is that plans are under way to do another Cloverfield after the $30-million picture set a January box office record on the weekend."
