Roman Polanski is handed a prize for directing the thriller, while the Oscar-nominated drama takes a kudo for foreign film.
France has celebrated the achievement in film-making by holding Cesar Awards on February 25, two days before 2011 Academy Awards takes place in Hollywood. "The Ghost Writer" grabbed four prizes at the Friday night event, for best director, adapted screenplay, original score and editing.
"I'm not used to making speeches," Roman Polanski said when accepting his prize. The director then went on crediting his wife, children as well as his production and artistic team before ending it with a simple "merci, merci, merci."
The helmer additionally shared best adapted screenplay gong with Robert Harris. "I regret that Robert Harris isn't here tonight, he deserved this, but I promise he'll have it tomorrow," Polanski said of his co-writer.
Also grabbing multiple nods at the 36th annual ceremony was "Of Gods and Men". The movie, loosely based on the life of the Cistercian monks of Tibhirine in Algeria in the 1990s, snatched three trophies for best film, cinematography and supporting actor, with the latest one honoring Michael Lonsdale's performance.
"The Social Network", which has been champion at various Critics' awards, only took home one kudo which is for foreign language film. The animated film prize went to Sylvain Chomet for "The Illusionist", while the other winners can be seen here.
2011 Cesar Awards, which was presented in Paris, was attended by a number of Hollywood stars like Diane Kruger, Christoph Waltz and Quentin Tarantino. Jodie Foster, meanwhile, was in charge as the ceremony's president.
