Paris and was the highest-grossing film ever in Quebec, making $2.2 million in the province alone. Outside Quebec, the film made $1 million in Canada. In
France, it drew an audience of 1,236,322 people, the highest for a

Metacritic assigned the film a weighted average score of 60 out of 100, based on 5 critics, indicating "mixed or average reviews".
Roger Ebert gave the film three stars, saying that despite the sexual dialogue, "the real subject is wit", and comparing it to
My Dinner with Andre.
Vincent Canby of
The New York Times wrote "Not since
Alain Tanner's
Jonah Who Will Be 25 in the Year 2000 has there been a comedy that so entertainingly and successfully expresses itself through intelligent characters defined entirely in their talk", and called the cast, including
Rémy Girard and
Pierre Curzi, "excellent". Rita Kempley of
The Washington Post found most characters unlikable but wrote "
The Decline of the American Empire is certainly the year's most intellectual work, a frequently funny, unrepressed meditation on midnight in North America". Peter Keough of the
Chicago Reader wrote "The laughs come easy in
Decline, but also a bit guiltily when you recognize that this hip sex comedy is actually a reactionary tract", given what he saw as the ending's victory for "traditional heterosexuality" while the homosexual character had an STD.
David Denby of
New York magazine panned the film, calling it "pompous and tiresome". In France, many critics highlighted the film's use of Quebec's natural landscape. The
Toronto International Film Festival ranked it in the
Top 10 Canadian Films of All Time twice, in 1993 and 2004. Shortly after the release of the sequel
The Barbarian Invasions in 2003, the
British Film Institute called
The Decline of the American Empire "a witty and provocative look at the battle of the sexes". In 2011, marking the 25th anniversary of the film, Isabelle Houde of the Montreal-based
La Presse remarked the film was daring for 1986 in portraying homosexuality as normal. In 2023, Barry Hertz of
The Globe and Mail named the film as one of the 23 best Canadian comedy films ever made.
Accolades The film won nine
Genie Awards in 1987, including
Best Motion Picture and
Best Director and
Best Original Screenplay for Arcand. It also received the
FIPRESCI Prize at the
Cannes Film Festival. The film was nominated for the
Academy Award for Best Foreign Language Film at the
59th Academy Awards, the first Canadian film so honoured.
Garth Drabinsky, who handled the distribution of the film in the United States, hired Renee Furst to promote the film's Oscar nomination.
Telefilm Canada contributed $50,000, under the stipulation that it would only be repaid if the film won an Oscar.
The Assault from
the Netherlands would eventually win he award.
The Decline of the American Empire's sequel,
The Barbarian Invasions (
Les Invasions barbares), would go on to win Canada's first Oscar in the category
in 2003. ==Sequels and proposed remake==
