2003 television film based on the life and career of actress and comedian Lucille Ball. Listed in various sources as a Canadian/USA co-production, this includes quite a lot of New Zealand talent in the cast so even if it wasn't shot here (i suspect it was but haven't found any evidence to prove it) it's worth a mention as a lot of local talent must have been left the country on the same flight to where ever it was filmed...
