Mr Kenwright, who remortgaged his home to pay for the club, became chairman in 2004, succeeding Sir Phillip Carter.
He has confessed the job was the culmination of a lifelong dream. Now he is fulfilling his other passion - Westerns.
Talking to Simon Mayo on BBC Radio Five Live, Mr Kenwright said: "I'm directing a movie next year. I'm giving up three months of my life to go to Arizona."
He said he would be flying out in May and would spend the summer filming. The movie has not yet been cast. Comparing his idea for the movie set to something out of Gunfight at the OK Corral, he said: "All my life I've loved Westerns."
He added: "It's a great script and I'm passionate about it."
The movie is adapted from a 1999 book by author Trevanian and tells the story of Twenty-Mile, a dying silver-mining town in 1898 Wyoming. When escaped murderer Hamilton Leider concocts a plan to rob the mine, it is down to young drifter Matthew to lead the town's violent struggle for survival.
