Now that we’ve had a few days to digest the gloriously moronic (and NSFW) trailer for John Cusack’s upcoming time-travel comedy Hot Tub Time Machine, we can’t help thinking that it will either be the stupidest movie Rob Schneider never made or a so-dumb-it’s-brilliant instant classic. 

Well, after speaking with Cusack about it, we’re more convinced than ever it will be the latter. 

“We just finished shooting it a week or so ago,” says Cusack, who stars in the film with Rob Corddry, Craig Robinson, and Clark Duke and succinctly describes the film as “four idiots who are thrown back into the ’80s to go boldly where men have gone before.” “It’s a ridiculous film. You’re pretty much either sold with the title, or it’s not for you.”

By the way, if you haven’t seen the trailer, here you go… 

We’ll admit it. The first time we watched this thing, our immediate reaction was: What is a guy as A-list and respected as Cusack doing in a movie about a hot tub time machine called Hot Tub Time Machine? But if you think about it, it makes perfect sense — it’s nothing more than a return to the kinds of movies the actor made at the beginning of his career.  

In fact, just ahead, allow us to take you on a stroll down numbskull memory lane…

The Sure Thing (1985)

Better Off Dead (1985)

One Crazy Summer (1986)

So where do you stand, PopWatchers? Will Hot Tub be painfully stupid or so-dumb-it’s-brilliant? What do you think about Cusack’s decision to dig back into his goofball past for this project?
