"People think that when you’re the star of a film, your time must be chock-full with endless minutia—appearances, conversations, getting 'into character,' and so on. But when you’re the star, you end up just sitting around a lot. For a single shot to take place, for instance, a whole series of organized events have to be set in motion: The 3D crew has to gauge the shot, the cinematographer has to line up the camera, the lighting crew has to arrange its lights and shades, the set has to be rearranged or otherwise moved into place, the wardrobe and hair departments have to prepare the actors—and through all of this, the actor just sits and waits. In fact, actors will often sit and wait so for so long that "body doubles" will sometimes be hired just to sit and wait in the appropriate place for the actors. So when you see James’s character with his arm trapped under a rock in 127 Hours, what you don’t see is that there was an assigned reading under the rock with it. When he’s playfully wrestling with a genetically-enhanced chimpanzee in Rise of the Planet of the Apes, just off to the right of the shot was a stack of books.

"The truth is, if you’re an A-list Hollywood star like James Franco, and are willing to put the time into earning a Ph.D, you may actually have more time to read than many of your colleagues. Heck, you don’t even have to worry about the grocery shopping, laundry, and other sundry tasks that every other poor graduate student in the country has to worry about. After visiting Detroit, the thing I found myself wondering was not 'How does James do it?' but rather 'Why aren’t more Hollywood actors earning Ph.Ds?'"
