Jack and Jill is a 2011 comedy film starring Adam Sandler in dual roles as twin siblings. Jack, an ad executive, is a content family man with a loving wife Erin (Katie Holmes) and their two kids. On the other hand, his twin sister Jill is the complete opposite - loud, needy and bothersome. Jill arrives in LA to spend Thanksgiving with Jack, but soon overstays her welcome and causes chaos in his life.
Throughout the film, Jack is forced to deal with his sister's antics, which include ruining his business dinner, causing a scene at a basketball game, and even getting involved in a romantic interest that causes more trouble for the family. Meanwhile, Jack is also struggling with his own personal and professional pressures, leading to stress and tension within his marriage.
The film features several celebrity cameos, including Shaquille O'Neal, David Spade, and Al Pacino, who plays a fictionalized version of himself and becomes infatuated with Jill. The plot revolves around Jack's attempts to get his sister to leave, while also trying to win back a big advertising account and maintain his relationship with his family.
Despite negative reviews from critics, the film was a box office success, grossing over $149 million worldwide.
