The movie is In a World..., written, directed by and starring Lake Bell, previously best-known as an actress in such things as HBO's How to Make It in America and the popular comic webseries, Childrens Hospital. The title comes from the all-too-common line that begins so many movie trailers. And the story concerns a young woman's efforts to break into the very-closed society of male-only voiceover announcers for movie trailers.
It has a very nice cast, as well, including Ken Marino (who starred and directed the hilarious webseries Burning Love, a spoof of The Bachelor, that I wrote about on the Huffington Post in its early days, long before it was picked up and re-run on the E! Channel), Rob Corddry, Eva Longoria, Nick Offerman, and Geena Davis,
Here's the trailer.
