Filmmakers like a time machine. The latest preposterous vehicle to join the fray features in Safety Not Guaranteed, in which the putative time traveller's vehicle of choice turns out to be a speedboat, dressed with aerials and other non-aerodynamic objects.
The most famous time machine in cinema is, of course, the DeLorean of Back to the Future. Mike Myers used a car in Goldmember while Bill and Ted were transported by phone booth. Less obvious devices can be found in Teenage Mutant Ninja Turtles III (a Japanese sceptre) and Time Bandits (a map).
Nothing, though, beats the Jacuzzi in Hot Tub Time Machine, a terrible film worth watching just to hear Craig Robinson say the immortal line "It's a hot-tub time machine", as if it were just another everyday object.
