Factual error: One of the questions Jamal has to answer is "Who invented the revolver?" to which the answer is given as Samuel Colt. Colt didn't invent the revolver, or even claim to invent it - he merely took a form which had existed for many years and substantially improved it. For example, Elisha H Collier patented a flintlock revolver in 1818 when Colt was only 4 years old which was produced in numbers for the British forces in India.
