CNN asked UCLA professor Jean-Luc Margot to go to the movies.
 
Margot isn't a film critic, but when the news network wanted an assessment of the scientific accuracy of the new movie "Gravity," in which Sandra Bullock and George Clooney play astronauts in a damaged Space Shuttle, he was the expert they sought.
 
Margot is a plantetary astronomer in the UCLA College of Letters and Science.
 
After sitting through an advance 3-D screening of the film, which opens Oct. 4, Margot was interviewed by CNN in UCLA's planetarium about where the movie's science was accurate and the couple of spots in which it wasn't.
 
His overall impression? He liked the film very much and recommends it. "The quality of the sound and 3-D imagery was astounding," he said.

Margot provides a more detailed analysis of the science in "Gravity" on his UCLA website.
