A Biopic is a term used to indicate a biographical film. Biopic is an abbreviation of biographical motion picture. These films are usually based wither on the life of historical figures or non-fictional people and feature a dramatization of the events that occurred in their life.
The correct pronunciation of biopic is Buy-ow-pic. People sometimes pronounce biopic as buy-OH-pic, but this is mistaken. The reason this form is a mistake is that biopic is an abbreviation, therefore biopic should be pronounced like the two words from which the initial letters are taken, which in this case are "bio" and "pic".
