Obama's Big Studio Phone Bank

Lynton, along with wife Jamie, stopped by the Culver City phone bank on election day, where organizers expected between 600 and 700 volunteers to pass through the doors of soundstage 3. The Sony topper missed co-chairman Amy Pascal, who had already volunteered before 9 a.m.

Campaign bundler Jamie Lynton sported a custom-made silver necklace with the Obama rising sun logo. Top California Obama campaign staffer Mary Jane Stevenson gave Lynton the necklace after the 2008 election. Jamie Lynton began volunteering for Obama since "the day he announced" in 2007.

"I will be here until we get to declare victory. I sent out an email to about 550 people and tell them to get out here," Jamie Lynton said, moments before her husband walked up. The two jokingly discussed whether their eldest daughter had cut school to make phone banking calls with her parents.

Bizzers including Cameron Crowe and Julia Louis-Dreyfus had also stopped by to cold call residents in states including Colorado, Ohio and Wisconsin (Dreyfus even made a video of herself making calls, available on her website).

Volunteers estimated that California had made as many as a million calls on Monday, making it one of the most actively grassroots non-battleground states.

Several volunteers nearly wandered into the soundstage next door, where dozens of women were heading into a live taping of "The Ricki Lake Show."

Asked what the atmosphere was like at the nearby Sony lot, Michael Lynton said there was support for both sides, although he pointed out that most of the support for Republican nominee Mitt Romney came less from inside Sony and more from producers and others around the lot.
