Joseph Gordon-Levitt and Julianne Moore: Why Are They Hanging Out Together?

Both actors were spotted enjoying a casual stroll through the streets of New York City

The brand-new Dark Knight Rises trailer obviously isn't the only place one can catch a glimpse of Joseph Gordon-Levitt.

There's also the streets of New York City, where the actor was spotted yesterday strolling with none other than...Julianne Moore!

Wait. What?

Relax. Before you all start spreading romance rumors, it seems the two simply met for a business lunch.

Which makes total sense seeing how Moore will be in Gordon-Levitt's upcoming directorial debut, Don Jon's Addiction. Not to mention, Moore is happily married to director Bart Freundlich.

Of course, Gordon-Levitt's movie will also feature Scarlett Johansson.

Hmm, now there's a pair we wouldn't mind speculating on.
