Many reasons! Even little known actors will have trouble because of the risk involved. A bit part actor today can become a global icon tomorrow! Their monetary value can rocket within hours, and insurers don't like big risks! But apart from that, the circles in which you are perceived to move in are a factor. So, even if you're a film extra, you could potentially give CZJ a lift home, crash and injure her. The cost of the claim would be infinately higher than for an average Joe - so your car insurance is higher. Home insurance - same sketch. CZJ might visit and have an accident. I haven't got any specific companies that I could recommend, but speaking to a broker who can point you in the direction of insurers specialising in high risks would be your best bet. Hope this helps!
