Have you ever heard of Nollywood? Nollywood is the name of the Nigerian film industry. Nigeria is one of the largest film industries in the world LLYWOOD based on the large number of films produced, placing them right below India’s Bollywood and above USA’s Hollywood!
Born in around 1992, Nollywood is the youngest compared with the other two woods, and uses new forms of financial aid and production. Now it’s in adulthood, and bigger productions have become more regular. However, this was not always the case. Though movie theaters were very few in Nigeria during the earlier period, original stories were not. Although being short of money and experience, directors began to use video cameras to shoot their movies and sold them for home viewing. Even though this led to movies with low production value, the original stories immediately made them a hit. Today, the film industry is the largest employer after agriculture* and makes up 5% of Nigeria’s GDP.
Nigeria is a big player in the film industry and it is continuously improving its skills, taking on new challenges. Nollywood is known mainly for its comedies and dramas, but we are increasingly seeing scary movies and musicals.
Although sometimes heavily criticized* for low production values, Nollywood continues to grow fans worldwide. Nigerian movies now make up 11% of Nigeria’s non-oil exports*! The average movie is produced in 7-10 days on a budget* between £ 7,000-12,000 (Hollywood’s average is around £ 60 million per movie with one year production time). This is changing, however, as more filmmakers are receiving proper training and are trying to make films up to the international standard.
