So how did she win the Oscar for Dreamgirls (besides singing And I Am Telling You I'm Not Going)? Ummm, she won an Oscar precisely for singing "And I Am Telling You I'm Not Going." I thought she was so out of the world amazing when I first saw her, and every time I watch the movie, her line readings become more and more wooden. You can also tell how much editing creates that performance, try looking for a dialogue scene that features Hudson for more than a few seconds in each shot. Also, remember Condon was very open about how he had to do some sort of "boot camp" for Hudson to get her acting up to snuff.
