5 A Steve Martin Classic. Comedy at it's finest!cheekychihuahua | 11/05/2007 | See all cheekychihuahua's reviews (21)Top 100 Books Reviewer This is the film that put Steve Martin on the map of Comedy. Steve plays Navin Johnson, an adopted son of a poor black family. On his birthday he decides that he needs to see the world and get out to find out what his "special purpose" is, I won't give anything away but he certainly does! On his travels, he comes across a lady motorcycle circus rider, I use the term lady loosely!! Dodges his way from a nutcase with a shotgun, attracts a scruffy dog and meets the love of his life. A simple act of helpfulness makes him a millionaire by his chance invention of the "opti-grab" handle for glasses, right through to him losing it all in a bizarre twist of fate. So many classic one liners, and gags galore, you will laugh your way right through this film, so make sure you don't leave the room!
