A Strange Bet

Long ago there lived two brothers. They were good and well with their life. Once they made a strange bet. That bet changed their life.
Their bet was about a bank note. At that time, the central bank of that country issued two notes, each valued a million pound. The two rich brothers challenged each other about that. One of the brothers said that a man with that note could survive a whole month without spending any other money. The other disagreed and said that he would end police custody. They bet on that. And for this they both one of the bank notes.
So they searched for a person who was unfamiliar to the city and had no known person from whom he could get help. If the person had one, he might get financial help. They also looked for a impotent one. Finally they found a person. They gave him the note and a letter. But they didn't say anything about the bet.

The man was in the need of money. He was too hungry that he directly went to a restaurant for dinner. He ordered foods of many kind and ate full appetite. At time of payment he brought out the note from the envelop and got shocked. The manager also got shocked. He apologized to him and said,"Sorry sir. I understand you're a rich man. You don't have to pay now. You can eat anytime when you want and made your payment when you wish."
The man getting out of the restaurant open the letter. There was written that he had to spend a whole month with this note without spending it and taking help from others. The story continued for the whole month how he survived the month.
This was the story of the movie "Man with a million pound note" that released on 1954. I'm searching for the full movie. Can any of you suggest any site ?
