From walking around in full costume on location to chilling with co-stars between shots, here's a look at how Hollywood's biggest star spend their time on set while filming their big blockbusters!
The celebrated comedian was spotted shooting exterior scenes for the second season of his acclaimed crime comedy Only Murders in the Building in New York City's Astoria Park on Jan. 19.
The 16-year-old multitalented star is seen filming her new series, Money With Marsai Martin, in New York City, in collaboration with In The Know, Verizon Media's new video platform. Martin's new finance series -- featuring interviews with industry experts and information on how to plan for your financial future from a young age -- premieres July 27.
Mindy Kaling and Matt Damon
The high-profile commercial is especially meaningful for Kaling, as she got her big show business break playing Damon's BFF Ben Affleck in her 2002 play Matt & Ben, which she co-wrote with her pal Brenda Withers.

It looks like Danny Castellano (Chris Messina) will be competing with yet another hot doctor. James Franco showed up on set of The Mindy Project on July 24, 2013, and leading lady Mindy Kaling couldn't help but Instagram a pic of the moment. She captioned the pic, writing: "Just three dudes chillin #themindyproject."
Franco will appear in a two-episode arc on the hit Fox show, playing Dr. Paul Leotard -- a former model -- who replaces Mindy at Shulman & Associates while she's in Haiti on a volunteer mission. The reason for the abrupt career change? Franco's character accidentally walked off a runway at fashion week and was saved by a pregnant woman.

In the ep, Potts plays Sharon, Stef's colorful and talkative mother who comes into town for a visit with the family. Collins was cast as Lena's father, Stewart, an old school guy who has a unique knack for diplomatically dealing with their big brood.
