Re-heat the tub
Here is a Sky Movies fact- Hot Tub Time Machine remains one of the most underrated comedies of the last 10 years. Wry, knowing and packed with great jokes and 80s references, it should have been huge.
However, moderate success at the box-office was followed by strong performance in the home entertainment market which encouraged Fox to plan for a follow-up.
All of the original cast have signed up, except John Cusack, with whom, according to cast mate Craig Robinson, may yet be tempted as "negotiations are still going".
Hopefully, the sequel will be more than a wrinkled, lukewarm dip into the old bathwater.
