Steven Spielberg's biopic of Abraham Lincoln is so big its trailer has a trailer.

A teaser is now online to promote tonight's Google hangout with Spielberg and Joseph Gordon-Levitt, who plays Robert Todd Lincoln in the film.

Daniel Day-Lewis plays Lincoln himself.

The full trailer is out at 7 p.m.; the film opens in some theaters on Nov. 9 and nationally on Nov. 16.

From the Associated Press:

The movie filmed in Virginia also features Sally Field as Mary Todd Lincoln.

Supporting actors include Tommy Lee Jones, James Spader and David Strathairn.

Officials said the production employed more than 400 Virginia crewmembers and staff as well as about 1,200 actors and extras. The Virginia Film Office said the economic impact for the Richmond and Petersburg areas was more than $64 million.
