Making films in glamorous locations is helping to increase the level of risk in the global filmmaking industry, a report said.

The Global Filmmaking Map published by Aon rated 91 countries with a high or very high risk rating, compared with 85 countries in 2003.

Aon said the greatest risk facing today's filmmakers when on location overseas is disease.

The Congo, Zimbabwe and the Ivory Coast are considered to be among the riskiest places to film, the report said.
