In 1990, he made a cameo appearance in the sport/crime drama The Big Man, opposite Liam Neeson, and in which Grant assumed a Scottish accent.
The film explores the life of a Scottish miner (Neeson) who becomes unemployed during a union strike.
He is also known for appearing in period pieces such as The Remains of the Day (1993), Sense and Sensibility (1995) and Florence Foster Jenkins (2016).
Grant and Curtis saw it as an inside joke that the star, due to the parts he played, was assumed to have the personality of the screenwriter, who is known for writing about himself and his own life.
Though a hit at the box office, it was almost universally panned by critics.
