An internationally popular light comic actor, Grant's films have included the Richard Curtis-written Four Weddings and a Funeral, Notting Hill, and Bridget Jones' Diary, along with The Englishman Who Went Up a Hill But Came Down a Mountain and Sense and Sensibility.
Grant is also known for his long-time relationship with actress Elizabeth Hurley and for a 1995 sex scandal that led to Grant making what would become a widely remembered appearance on The Tonight Show with Jay Leno. His mea culpa on that show resulted in Leno's show regaining late-night dominance after a shaky start following the retirement of Johnny Carson. It also helped restore Grant's career. His Doctor Who appearance occurred four years later.
Russell T Davies approached Grant to play the Ninth Doctor but he turned down the role, thinking the show would not take off. He expressed deep regret in 2007 after seeing how successful the show had become.
