Hollywood.tv captures LINDSAY LOHAN in action. Seen here walking briskly, the actress isn't storming away from the paparazzi, she's filming a scene! All in a day's work: the actress finished up her duties in about an hour.

Later, gal pal SAMANTHA RONSON joins Lindsay on the set. The two hang for a bit before a big hug goodbye as Sam takes off in her black Porsche.
