Ryan Gosling got to work on the LA set of Gangster Squad last night. He arrived for filming with his assistant and his dog, George, by his side. Once in character, Ryan met up with Josh Brolin to take care of reshoots on the project. Ryan and Josh returned to their roles earlier this week while costar Emma Stone hit the beach with her boyfriend. Emma and a few friends helped Andrew Garfield celebrate his 29th birthday on Monday, and they were back together yesterday for a fun trip to Disneyland. Ryan's girlfriend, Eva Mendes, meanwhile, has been out and about on her own lately, showing off her cute Summer style around town.
