Eight years ago, it seemed perfect--Tina Fey had to play Sarah Palin. The demand was so great she came back to SNL to do some classic bits. Fey herself said she didn't see it, but even her young daughter saw the resemblance.
But not long ago, when I saw the trailer for Why Him?, I thought the lady playing Bryan Cranston's wife was Fey. For a second anyway. Then I realized it was Megan Mullally.
