Sean Connery started going bald when he was 21. In 'Dr. No' (he was 32 then) and any subsequent movies in which he has hair, he was actually wearing a hair-piece.

A mistake in translation saw the film being released in Japan with the title - "We Don't Want A Doctor".

The role of Sylvia Trench was originally offered to Lois Maxwell, who instead went on to play "Miss Moneypenny" for the next 14 Bond films.

The scene in which Dr. No's men fire at Bond had to be shot twice. The first time, a detachment of U.S. Navy officers who were on leave ran over to the bay where filming was taking place to investigate the gunfire.

In the first draft of the script, "Dr. No" was a monkey .

Roger Moore was Fleming's original choice to play 007, but he was under a network contract for the television show "The Saint". Other actors who were considered for the role of James Bond included Cary Grant, Trevor Howard, Rex Harrison and David Niven - he would play the role of Bond in the spoof 1967 film "Casino Royale".

Ursula Andress was offered the role after the producers saw a picture of her in a wet T-shirt contest.

In the scene in Dr No's apartments, Bond does a double-take at a painting displayed on an easel. It was in fact a copy of Goya's "The Duke of Wellington", the original of which had been stolen in a raid on a museum shortly before filming began. Producers thought that it would be interesting to conceive that "Dr No" himself had arranged for the real life theft.

Ursula Andress was dubbed throughout the film by Monica ver der Zyl, with the exception of when she sings "Underneath The Mango Tree" when she first appears. Her singing voice was then provided by actress Diana Coupland, best known for her role in the 1970's British sitcom "Bless This House.
