In “The Muppets,” three hopefuls from Kansas come to Los Angeles with a plan. Gary (Jason Segal) and his long term girlfriend, Mary (Amy Adams) are planning their 10 year anniversary dinner and have chosen downtown L.A. as a backdrop. The couple decides that they should bring Gary’s brother Walter, (voiced by Peter Linz) who is a Muppet and is a fan of The Muppet Show which has a studio in Hollywood.
