WOW I gotta say this looks like an amazing movie! Bradley Cooper and Lady GaGa? YES PLEASE. If you are familiar with the original movie from the 70's then you know what it's all about. He's a star on the decline, she's an aspiring star and he falls in love and helps her along the way. Seems pretty simple to me. But watching this trailer makes me think there is a lot more to the story than just that, so I can't wait to see it. And just so you know, the one from the 70's is actually the 2nd re make. Yup, this movie has been done 4 times. 1st in 1937, then again in 1954, and then in 1976.
Just for fun I found the trailer from the 1976 version.
