10 Movies That Changed Hugely From The Trailers

5. Star Trek Beyond

The curious gulf between Star Trek Beyond's much-loathed first trailer and the final movie isn't so much a result of the film being excessively tinkered with in post-production as it is Paramount opting to market the film in the most cynical way possible.

That first trailer played-up a lighter-than-air tone where ludicrous set-pieces would take pride and place over the thoughtful philosophy the franchise is known for.

Invoking director Justin Lin as the guy who brought us the best Fast and the Furious movies didn't really help, nor the overpowering use of The Beastie Boys' iconic "Sabotage" (as was memorably used in the 2009 Trek reboot).

"Desperate" is the word that comes to mind with this trailer, with Paramount likely feeling the pressure to play-up the schlocky action and slick one-liners after the previous film, Star Trek Into Darkness, performed milder than expected at the box office. Basically, it felt like an attempt to cash-in on the success of goofball space opera Guardians of the Galaxy.

Writer Simon Pegg even criticised the trailer both before and after the movie's release, insisting that it wasn't reflective of the film's actual tone, and that it effectively spoiled the callback to Sabotage, which is cleverly employed in the film's climactic set-piece. Post-release, Pegg also blamed the film's middling box office on the pandering marketing.

And indeed, the final film was quite tonally distinct from this trailer, with Star Trek Beyond ultimately turning out a surprisingly emotional and character-driven homage to the original TV series. Furthermore, the action and comedy elements were decidedly more reined-in than the trailer implied.

Though re-shoots were undertaken a few months ahead of the movie's release, and it's possible that scenes were re-worked to appeal more to the core Trek fanbase, by most accounts this disconnect was entirely the fault of the marketing.
