Twilight star Robert Pattinson was out and about early today in Central Park, NYC, filming scenes for his latest movie, Remember Me.

Rob was actually looking a bit tired and tried to liven himself up by knocking back a giant coffee while puffing away on a cigarette.

He then began shooting scenes...where he seemed to be talking away to a giant rabbit at the famous Alice in Wonderland statue.

Is all this hard work sending him crazy? Give the guy a rest.
