its a vh1 movie...didn't they make that awful michael jackson biopic?
You can't expect big studio money because it wouldn't make the money like a biopic of Johnny Cash or Ray Charles would where they got real strong acting efforts and two excellent actors to portray them
LiL Mama as far as I know doesn't have strong performances or i wasn't even aware she ever acted before...so yeah its disrespectful but you would have to at least wait for the performance
sad thing is if they actually did a search for real actresses that haven't had exposure they could find a left eye lopez who looks more like her and is probably a better actress but somebody in that studio must owe lil mama's agent a favor
