Kat Dennings knew her real name "wasn't going to work" for her acting career when she was just nine years old.
The 38-year-old actress - who made her official onscreen debut in a 2000 episode of 'Sex in the City' having previously featured in commercials - was born Katherine Litwack but quickly chose a stage name for herself as she felt her real surname couldn't "be displayed" on promotional posters.
