Oscar-winning actor Colin Firth is expected to leave Malta today after taking part in a biopic based on the story of Donald Crowhurst, an amateur sailor who attempted to circumnavigate the world alone in 1968 during the first Golden Globe yacht race. Rachel Weisz and David Thewlis will also be starring in the film as Crowhurst’s wife and press agent, respectively. Filming is taking place at the Mediterranean Film Studios’ water tanks in Kalkara, whose facilities were recently improved to attract more film productions.
