If the invention of cinema was to be compared to one of the many genres which later came to dominate the art form, it might be regarded as a whodunnit. Given the claims and counterclaims for the sole right to be known as the inventor of cinema, perhaps the specific whodunit in question is JB Priestly’s An Inspector Calls, in which everyone has some degree of culpability. Among the ‘suspects’ were American Thomas Alva Edison; the French Lumière brothers, Louis and Auguste; British-based Frenchman Augustin Louis Le Prince; and the British William Friese-Greene. Like movies themselves, however, the hunt for the sole inventor of cinema is an illusion.
