For Kermit the Frog, it's not always easy being green, but it's especially hard when the world's most sought-after criminal is the exact same froggy color. In the new trailer for "Muppets Most Wanted," Kermit is mistaken for bad-guy frog Evilen Froggen and then incarcerated by Tina Fey. The "SNL" funny woman isn't the only human star to make an appearance in the preview, which includes shots of Ricky Gervais, Ty Burrell, Zach Galifianakis, and P. Diddy, among others. A follow-up to the 2011 film "The Muppets," "Muppets Most Wanted" will hit theaters in the spring of 2014. Take a look at the new trailer above.
