This comedy from director Dennis Dugan (Happy Gilmore, Big Daddy) stars Adam Sandler as Jack Sadelstein, a successful advertising executive who lives in Los Angeles with his beautiful wife (Katie Holmes) and kids and who seemingly has it all.

However, once a year his perfectly peaceful life is shattered with the arrival of his twin sister Jill (Adam Sandler) who comes to visit every year for Thanksgiving.

Unlike many sets of twins, Jack & Jill are very different people and so it isn’t long before Jill's neediness and passive-aggressiveness drives Jack crazy, turning his normally tranquil life into a dreadful, if hilarious, nightmare.
