What's on tap for "Hot Tub Time Machine 2"? Co-stars Clark Duke and Adam Scott aren't telling - though the former did offer one compelling tease during my interview with the pair earlier today.

"We don't know that much about this movie yet. What can you tell us about it?" I asked the actors during the junket for their upcoming big-screen comedy "A.C.O.D."

"We don't [know much about it] either," lied Duke (the movie was filmed this summer).

"Are you guys traveling back into the past again?" I pushed. "Or is there a little 'Back to the Future 2' element where you go into the future?"

"I don't know how much we're supposed to say or give away yet, like, I don't wanna get in trouble," said Duke. "But the 'Back to the Future 2' thing you said is pretty on the nose."
