About Jessalyn Gilsig
Jessalyn Gilsig’s television career reaches well beyond Siggy. She plays Lauren Davis in Boston Public, Gina Russo in Nip/Tuck, Shelley Hayes in Friday Night Lights and Terri Schuester in Glee. Those recurring and ensemble roles make contemporary American television a substantial part of her work, in contrast to Siggy’s struggle to retain standing in Kattegat.
Glee is the most recognizable next stop for many viewers, but Boston Public offers another extended television role. Comparing those performances with Siggy brings out the different uses of an ensemble actor: sometimes the character drives a domestic storyline, sometimes she changes the balance around the leads. Nip/Tuck offers a further route into that contemporary television career.
