Uptown Saturday Night grossed $7,400,000 in the US, surpassing its production cost of $2,500,000. It was on the list of top 50 highest-grossing films at #3, just three months after its release. The film received mixed-to-positive reviews upon release.
Vincent Canby of the
New York Times wrote that the film "is essentially a put-on, but it's so full of good humor and, when the humor goes flat, of such high spirits that it reduces movie criticism to the status of a most nonessential craft".
Gene Siskel of the
Chicago Tribune gave the film 3 stars out of 4, calling it "an old-style comedy revue in which each actor has his chance to crack up the audience with one big scene ... [Poitier] derives natural comedy through the simplest of actions, simply because he's Sidney Poitier. Whether it's waiting for a bus or calmly listening to a boastful friend, Poitier grabs our attention by letting us see him as a regular guy".
Kevin Thomas of the
Los Angeles Times called it "the funniest film since
Blazing Saddles and surely one of the year's most enjoyable movies, the old-fashioned kind that leaves you feeling good when it's over".
Penelope Gilliatt wrote that Richard Wesley's script "has managed to say something farcical with courageous and truthful underpinnings about Black ways of escape into a world that is full of far more fun than any that more privileged whites ever seem to create". Among negative reviews, Gary Arnold of
The Washington Post wrote that "while the film is a welcomed change from the many blaxploitation films of recent years, neither the vehicle nor the performers are able to get off the ground". Paul D. Zimmermann of
Newsweek wrote: "Poitier is not an inventive comic talent — he is erratic behind the camera and amiable but not funny in front of it. When the funny set pieces stop, the film sputters — but not before delivering a carnival of fine comic characters".
Variety called the film "uneven", opining that "too much of the time
Uptown Saturday Night just lies there, impatiently waiting for more inventive comedy business and a zippier pace than the sober Poitier seems able to provide". Walter Burrell of
Essence magazine wrote "one walks away a bit dissatisfied...One is left with the feeling these great talents could have used a vehicle more suited to their abilities". ==Television pilot==
