Twins (rendered in its title sequence logo as TWiiNS) is a 1988 American buddy comedy film directed and produced by Ivan Reitman.

Vincent owes money to a loan shark and makes a living stealing cars and selling them for parts.

Julius was raised on a South Pacific island by Professor Werner, one of the scientists from the experiment, who put him through intense physical training and extensive study.

Julius eventually tracks Vincent down in jail, where he is being held for unpaid parking tickets and driving with an expired license.

Vincent steals a car from a parking garage run by his buddy (to sell to a chop shop) and finds a prototype fuel injector in the trunk that was to be delivered to industrialist Beetroot McKinley in Houston, in return for $5 million.

Vincent decides to pose as the delivery man, Mr. Webster, and deliver the fuel injector himself so he can collect the money and pay off his debts.

He reluctantly allows Julius, Linda and Marnie to accompany him to New Mexico to find Traven, while Webster begins pursuing Vincent.

They leave, unaware that the gardener was in fact Mary Ann herself, who did not believe their story, having been told she only had one son who died at birth.

She violently confronts Traven for concealing the truth and then tracks Julius and Vincent down to their workplace, where they share a warm reunion.

Each marriage produces a set of twins: Jude and Mare, and Vinnie and Linnie, and the couples are last seen meeting their mother and Professor Werner on an outing.

Edelman has scored three more films for director Ivan Reitman (Ghostbusters II; Kindergarten Cop; and Six Days, Seven Nights) whereas this was Delerue's only work for him.

The consensus states: "Though it offers a few modest pleasures for undemanding viewers, Twins leans too heavily on the wackiness of its premise to overcome its narrative shortcomings.

[13] Roger Ebert gave the film 3 out of 4 stars, calling it "engaging entertainment with some big laughs and a sort of warm goofiness".

[18] In September 2021, it was announced filming will commence in January 2022 in Boston, with Ivan Reitman directing, Schwarzenegger and DeVito reprising their roles as Julius and Vincent Benedict, and Tracy Morgan replacing Eddie Murphy as Schwarzenegger and DeVito's long lost triplet brother.

[20] In May 2023, Schwarzenegger confirmed that a sequel would not be made, as Reitman's son Jason put the idea to an end following his father's death.
