This Friday, "Idol" winner Jordin Sparks makes her feature-film debut in "Sparkle" as an aspiring Motown singer. Will it lead to Oscar gold as it did for Hudson? Considering the film's current Rotten Tomatoes score, it's not likely.
So, in honor of Sparks's role in "Sparkle," let's rank the acting skills of those who've made it to the big screen. (Apologies to Constantine Maroulis, Ruben Studdard and Fantasia, who've proven their acting chops, but only on the stage, TV or DVD.)
