Let's say there's an awards show for the Super Bowl commercials. One of the categories should be Best Cameo by an SNL Player.
Andy Samberg would definitely win. It was a funny and unexpected cameo in the Pepsi commercial starring Justin Timberlake (who collaborated with Samberg on the "Dick In The Box" music video for 'Saturday Night Live'). And he got a nice close-up for his troubles.
As for Chris Kattan in the Diet Pepsi Max blipvert (O'Bviously both ads were the brainchild of some 'SNL' fan)..... I'm a big fan of Kattan from his days on the show, but honestly, I had to be told in some blog that he was in the ad! I never made the connection that it had to be him and that he was fed up with the over-use of the song that underscored his best-known character on the show. I just figured that it was some guy who, like me, is sick of the song's extended shelf life.
What he needed was a good close-up to establish his identity.
