The Muppets Take Manhanttan (1984)
In this film directed by Frank Oz, the Muppets graduate from college and try to tackle Broadway. They suffer rejection and heartache, but Kermit's perseverance eventually pays off. But, just when the lights of the Great White Way are within view, the show's writer-director-star, Kermit, disappears. The third Muppet movie is notable for the introduction of the Muppet Babies as well as the long anticipated "marriage" of Kermit and Piggy (with a real-life minister playing the role of a minister-much to Kermit's surprise and chagrin!).
