Grant has mostly been a comedy (especially a romantic comedy) actor for almost all of his mainstream film career. He also never ventures to play characters who are not British. While some film critics, such as Roger Ebert, have defended the limited variety of his performances, others have dismissed him as a one-trick pony. Eric Fellner, co-owner of Working Title Films and a long-time collaborator of Grant, said, "His range hasn't been fully tested, but each performance is unique."  A majority of Grant's popular films in the 1990s followed a similar plot that captured an optimistic bachelor experiencing a series of embarrassing incidents to find true love, often with an American woman.
