In recent times there have been collaborations between Ghanaian and Nigerian crew and cast and a number of productions turned out. Many Ghanaian films are co-produced with Nollywood, the Nigerian film industry, and some are distributed by Nigerian marketers. Also, Nigerian filmmakers often feature Ghanaian actors and actresses in their movies and Ghanaian filmmakers feature Nigerian actors and actresses in theirs. Nadia Buari, Yvonne Nelson, Lydia Forson and Jackie Appiah all popular Ghanaian actresses and Van Vicker and Majid Michel both popular Ghanaian actors, have starred in many Nigerian movies. As a result of these collaborations, Western viewers often confuse Ghanaian movies with Nollywood and count their sales as one; however, they are two independent industries that sometimes share ''Nollywood''. In 2009, Unesco described Nollywood as the second-biggest film industry in the world after Bollywood.
