Lol are some of you serious with some of these responses? What obstacles has Beyonce had to encounter that would make for a good movie? Why would anyone but her fans even watch that... just go watch her HBO documentary.
Anyway, would love to see a biopic on Britney, especially centered around her fall from grace.
Britney's would be interesting, I think. Depending on how truthful they were to her story, because I imagine there was a LOT of manipulation/rank-pulling/general dodgy business behind the scenes before you even document her breakdown.
Gaga's, too. She'd have the whole conservative, Catholic childhood set up, then rebelling and dropping out of NYU to make it on her own, the record contract falling through, the drugs and general mess, then the big turning point and makeover into Gaga followed by her big break and becoming a global phenomenon. That's kind of a perfect 'how they made it' popstar biopic.
Assuming the rest of her life/career isn't overly dramatic (i.e. dying young), then it'd be cool if the film ended as she was just about to perform on her first major show. Flashes of her defining moments flashing during the credits.
