Around year 2006 through 2007, Nigerian filmmaker Frank Rajah Arase signed a contract with a Ghanaian production company, "Venus Films", which involved helping to introduce Ghanaian actors into mainstream Nollywood. This collaboration eventually led to extreme popularity of certain Ghanaian actors, such as Van Vicker, Jackie Appiah, Majid Michel, Yvonne Nelson, John Dumelo, Nadia Buari and Yvonne Okoro, arguably as much as their Nigerian counterparts. Furthermore, over the years; due to the high cost of film production in Nigeria, Nigerian filmmakers have been forced to make films outside Lagos in order to cut costs, mirroring the exodus of filmmaking in Hollywood from Los Angeles to cities like Toronto and Albuquerque, a process known as “"Runaway production"”. Several other producers as a result started shooting in cities like Accra, Ghana, channeling the savings into investing in better equipment, many of them trying to get their films onto the big screen.
