'What is Paul?' is the production blog for Greg Mottola's film 'Paul' written by and starring Simon Pegg and Nick Frost.

Here you will find all of the official behind the scenes videos being shot by Lance Bangs as well as the odd candid video or photograph taken by the cast and crew.

PAUL is a comedy about two sci-fi geeks who embark upon a pilgrimage in a RV to the center of America's UFO heartland: Nevada's infamous Area 51. While in the middle of that desert, the two friends encounter a fugitive alien by the name of Paul. Somewhat reluctantly, they embark upon an adventure that will change not just their lives forever, but also the lives of the friends and enemies they encounter along the way.
