Tumblr supporting the 2011 movie Rango.
Starring Johnny Depp and Isla Fisher.
Rango is a chameleon who lives in a terrarium and constantly seeks to fit in with his surroundings. He finds himself removed from his contemporary American southwest surroundings and ends up in an Old West town in the middle of the Mojave Desert called Dirt, which is populated by various desert critters garbed like characters out of Western fiction. Thinking himself a hero, Rango establishes himself as the town's sheriff, not knowing that people who have held that title do not fare very well in Dirt. In "an existential crisis", Rango comes to question everything about himself.
