Bastion of respectable entertainment journalism Us Magazine is reporting that Kristen Wiig, Andy Samberg and Jason Sudeikis are all planning to leave SNL at the end of this season. It wouldn’t be entirely surprising, as these three (plus Bill Hader) have the biggest movie careers of any current SNL castmembers, and have all been on the show since 2005. It may be time to move on! But with Mittens Romney set to take on Obama this fall, one may expect Sudeikis to stick around and keep playing the Stormin’ Mormon until his inevitable defeat in November (or stick around for 4-8 more years playing President Romney. I’m no Nostrodamus!). In any case, take the source into account and take this one with a grain of salt — but it does sound pretty reasonable. [via]
