The latest comedy ‘Hot Tub Time Machine’ references blockbusters like ‘Back to the Future’ and ‘Terminator’.

In the new movie ‘Hot Tub Time Machine’, John Cusack and others go back in time with a, well, hot tub time machine.

In the comedy they pay tribute to many other classic movies that feature time travel.

The gold standard of course is Back to the Future, with the flux capacitor sending Michael J Fox back in time.

One of the stars of that movie, Crispin Glover, is actually in ‘Hot Tub Time Machine’ as well.

Also, the Terminator series features lots of time travel, and this new movie pays homage to that one as well.
