Jack and Jill is a 2011 American comedy film directed by Dennis Dugan from a script by Steve Koren and Adam Sandler.

Released on November 11, 2011, by Columbia Pictures, the film stars Sandler in a dual role as the titular twin siblings, as well as Katie Holmes and Al Pacino.

It tells the story of an advertisement executive who dreads the Thanksgiving visit of his unemployed twin sister who overstays into Hanukkah at a time when he is instructed to procure Al Pacino's appearance in an upcoming Dunkin' Donuts commercial.

Growing up in the Bronx, Jill Sadelstein makes repeated unsuccessful attempts to capture the attention of her gifted twin brother Jack by injuring him or repelling others from him.

As an adult, Jack is a successful advertising executive who resides in Los Angeles with his wife Erin, their biological daughter Sofia, and their adoptive Hindu son Gary, who compulsively tapes various objects to his body.

Jill visits Jack for Thanksgiving and announces that she plans to depart at the end of Hanukkah, having an open-ended plane ticket, much to his consternation.

Jill proceeds through a list of activities that she has planned to accomplish during her visit, including being a contestant on The Price Is Right (she receives a variety of prizes after incapacitating herself while spinning the wheel), going horseback riding (she proves to be too heavy for a pony that collapses under her weight), and touring a studio.

Pacino agrees to work on the Dunkaccino advertisement on the condition that he has another date with Jill, so Jack invites her to accompany him and his family on a cruise.

Arriving in the Bronx on New Year's Eve, Jill discovers that the bank has foreclosed on her home after she discarded numerous bills that she mistook for junk mail.

Pacino arrives dressed as Don Quixote, his character in a Broadway production of Man of La Mancha, and reminds Jill that he cares about her but that other men deserve her more than he does.

The film features cameos from Johnny Depp, Regis Philbin (in his final film appearance), Dan Patrick, Shaquille O'Neal, Drew Carey, John McEnroe, Christie Brinkley, Bill Romanowski, Michael Irvin, Jared Fogle, Billy Blanks, Vince Offer, Günter Schlierkamp and Caitlyn Jenner (the latter prior to her transition, as Bruce Jenner) as themselves.

The website's critical consensus reads, "Although it features an inexplicably committed performance from Al Pacino, Jack and Jill is impossible to recommend on any level whatsoever.

[14] Common criticisms were targeted toward the crude humor,[15] product placement,[16] celebrity cameos,[17] and a sentimental ending that contradicts the film's mostly mean-spirited tone.

"[21] Andrew Barker of Variety said that the film's "general stupidity, careless direction and reliance on a single-joke premise that was never really funny to begin with are only the most obvious of its problems".

"[26] Tom Russo of The Boston Globe gave the film two-and-a-half stars out of a possible four, writing, "What's more genuinely wacky is what a kick this movie can sometimes be, completely in spite of its big, flat stunt.

"[28] Jack and Jill was in the top five of numerous critics' lists of the worst films of 2011,[29][30][31] ranking number one on those of People's Alynda Wheat,[31] the Miami Herald's Rene Rodriguez,[31] Time's Mary Pols,[32] The A.V.

[38] Five months before release and the film getting extremely poor reception, the film was mocked on South Park during the episode "You're Getting Old", in which Stan and his friends go to the movie theater to watch X-Men: First Class, a trailer depicts Adam Sandler's characters Jack and Jill as feces (the following episode, "Ass Burgers", first aired on October 5, showing the character Stan Marsh needing to intoxicate himself with alcohol to laugh at the film), and in Robot Chicken during Season 6 during the segment "Twist Endings", depicting Jill being Jack, and that the real Jill died when she was young; Jack is driven so insane by the revelation that he immediately smashes his mirror and ends his life by slitting his throat with one of the broken mirror pieces.
