LOS ANGELES - John Cusack and Rob Corddry have boarded the comedy "Hot Tub Time Machine."

The MGM project follows a group of guys who have grown frustrated with their adult lives. They return to the ski lodge where they partied as teens to find answers and are transported to 1987 via their hot tub, a bubbly time machine.

Craig Robinson ("The Office") is in negotiations to join the cast. He, Cusack and Corddry will play the three best friends. Director Steve Pink is polishing the script ahead of a planned April 20 start date in Vancouver.

Cusack has "Shanghai" and "2012" in the can, while Corddry last appeared in "W." and "Harold & Kumar Escape From Guantanamo Bay." Robinson, best known for playing Darryl the storeman on NBC's "The Office," stole scenes in "Zack and Miri Make a Porno."
