Warner Bros. has released the first trailer for A Star is Born. Directed by and starring Bradley Cooper, the film follows Cooper as a musician who sees something in a bright and shiny star, Lady Gaga, and takes her under his wing. Once she begins to have success however, he begins to resent her thus straining their relationship. This is Cooper's directorial debut and he appears to have crafted a terrific drama with Gaga more than holding her own in her debut as an actress. A Star is Born opens October 5.
