Synopsis

Muppet Treasure Island was the sixth feature film to star The Muppets, and the second produced after the death of Muppets creator Jim Henson. Released in 1996 and directed by Jim Henson's son Brian Henson, it was one of many film adaptations of Robert Louis Stevenson's Treasure Island.
As in the earlier Muppet Christmas Carol, the key roles were played by human guest stars, while the Muppets filled in supporting roles. Tim Curry plays Long John Silver and Kevin Bishop is the putative protagonist Jim Hawkins. Muppets Kermit the Frog plays Captain Abraham Smollett, Fozzie Bear is Squire Trelawney, Sam the Eagle is Mr. Samuel Arrow and Miss Piggy is Benjimina Gunn. Following their success as the narrators of The Muppet Christmas Carol, The Great Gonzo and Rizzo the Rat appear in specially-created roles as Jim Hawkins' best friends.
While the movie never says what ocean they cross, they do refer to it as the "Big Blue Wet Thing." Silver (using the stars) determines they are heading southwest, which the map shows them crossing the Atlantic Ocean as they set off from England.

"The best muppet movie yet" Paul Wunder, WBAI RADIO
