There's a touch of Groucho in Gustave's loping run, attraction to rich dowagers, and arch one-liners, and something of Stefan Zweig in his groomed mustache, practiced bonhomie, and what Hannah Arendt, not a fan, termed the writer's "hypersensitivity to social humiliation." (Interestingly, Anderson has also cited Eichmann in Jerusalem as an influence on his film.)
