Tobey Maguire Pictures Running With Carey Mulligan

Tobey Maguire and Carey Mulligan kicked off their Saturday with a jog on the beach in Sydney. The Great Gatsby costars were joined by a few other pals for the run, which ended with some relaxing time in the sand. Tobey's wife, Jennifer Meyer, and their kids, Ruby and Otis, met up with the group after traveling to Australia to be close to Tobey during filming. He started working Down Under last week, when he and Leonardo DiCaprio were spotted on set driving a fancy old car around. Leo wasn't on hand for the weekend fun, though he was apparently busy with girlfriend Blake Lively. She made the trip to visit him during a break from production on Savages, and the duo reportedly celebrated Blake's 24th birthday with a romantic dinner. It doesn't look like Blake and Leo's busy schedules will slow down any time soon, since Leo just signed on for Martin Scorsese's remake of The Gambler.
