Hot Tub Time Machine 2 is a 2015 American science-fiction comedy film directed by Steve Pink and written by Josh Heald.

The film stars Rob Corddry, Craig Robinson, Clark Duke, Adam Scott, Chevy Chase, and Gillian Jacobs.

John Cusack, who played Adam Yates and produced the first film, does not return in the theatrical cut, but has a brief cameo in the unrated version.

The next day, they attend the popular television game show Choozy Doozy, where contestant Nick is required to have virtual reality sex with a man.

Essentially, Jacob becomes disillusioned with the misadventures and leaves the group to get drunk at Gary's club and to then commit suicide by jumping off an extremely high building.

When the guys see a news report where Brad, an employee of Lougle, invents nitrotrinadium, the ingredient that activates the hot tub time machine, they suspect he is the killer.

However, Paramount's marketing department believed that title would be confusing to audiences and named the film Hot Tub Time Machine 2.

[11] Reviews were generally negative, with The Hollywood Reporter calling it a "flop-sweaty cash grab that gives a bad name to sequels in which key talent has jumped ship.
