Life is a state of mind.
After Being There was published, author Jerzy Kosinski got a telegram from its lead character Chance the Gardener: "Available in my garden or outside of it". Kosinski dialed the accompanying telephone number and Peter Selelrs answered. Sellers indeed got the part and gave an indelible performance (winning National Board of Review and Golden Globe Best Actor Awards and an Academy Award nomination) in this modern comedy classic.
Isolated all his life in a Washington, DC, townhouse, Chance knows only what he's seen on TV. Cast into the world, he stumbles into the inner circle of political power brokers (including Melvyn Douglas in his second Oscar-winning role) eager for "sage wisdom". As Chance might say, you'll like to watch.
