Lady Gaga and Bradley Cooper wow fans on A Star is Born red carpet

Bradley Cooper directed and co-stars with Lady Gaga in A Star is Born, which is the most buzzed-about film at this year's Toronto International Film Festival. It's a remake of the 1937 film of the same name, which was first remade in 1954 starring Judy Garland and then in 1976 starring Barbra Streisand.

Bradley Cooper also co-wrote the screenplay, which is set in modern times. He plays a country singer whose star is fading, but who meets a young singer (Lady Gaga) who's just starting out, and helps her achieve fame.
