No, it was actually Zooey Deschanel, but based on how she performed in the sketches, her similar appearance, and the lack of anything really amusing tonight it was easy to make that mistake.
Bill Hader's Clint Eastwood was spot on, the second commercial was the best one, but a lot of these sketches were not clever at all, and Nicolas Cage finally meeting Andy Samberg's Nicolas Cage was disappointing. The "I was only able to appear in 90% of films, bringing shame on my dojo," line was good though.
SNL has surely seen better days. Too much singing and bad accents tonight.
