Now: Laura Prepon – a.k.a. Donna Pinciotti
Without question, Laura Prepon’s most famous character, after Donna, is the role of Alex Vause on the Netflix smash hit Orange is the New Black. She drastically changed her hair color and her overall look, but yet it’s still hard to see her as anyone other than Donna. Prepon has done some mainstream films here and there, but the overwhelming success of the Orange is the New Black has kept her far busier than she expected.
