Bill Murray "regrets" not asking Gene Hackman and Michael Gambon for more advice when he had the chance.
The 74-year-old actor worked with the late Hollywood legend - who, along with his wife Betsy Arakawa, was found dead on 26 February in different rooms of their home - on 2001 movie 'The Royal Tenenbaums', while he acted with Gambon in 2004's 'The Life Aquatic with Steve Zissou'.
