Muppets Most Wanted opened this weekend (unfortunately, to softer numbers than expected despite rave reviews), and star Tina Fey said that during filming, the muppets were actually more professional than most actors. Of course, muppets are manipulated by puppeteers, but it's a pretty choreographed performance.
In the video above, Fey says she had to remind herself not to screw up her one line during Kermit's Shawshank Redemption prison sequence. She also says that if you want to rekindle that Liz Lemon-Jack Donaghy chemistry, you'll either have to watch reruns or write "creepy fan fiction." We'll go with reruns.
