10 Amazing Trailers That Tricked You Into Seeing Terrible Sci-Fi Movies

10. Suicide Squad (2016)

DC may stand for Detective Comics, but with their cinematic universe, maybe they should switch it up to Disappointing Crap.

It's hard to imagine a time when anyone was excited about this dumpster fire of a movie. The universally panned dark comic-book flick was a major setback in the DCEU and a sign to long-term DC fans that their cinematic ventures were nothing more than paint-by-number corporate shells masquerading as comic-book movies. But, when this trailer came out, it was a whole other story.

This explosive Comic Con ad had so much going for it, including the chilling opening monologue from Viola Davis as Amanda Waller and beautiful use of the song "I Started A Joke". Plus, seeing the soon-to-be iconic Margot Robbie as Harley Quinn for the first time was so exciting - not to mention the infamous Jared Leto as The Joker, which was (at the time) really tantalising. This trailer made the film look dark, frightening and even profound.

DC only kept this up as well, as the next trailer (scored by Bohemian Rhapsody) was also kickass. Sadly, in the end, the movie ended up being an irredeemable and jumbled mess, with Robbie's Harley Quinn acting as the only saving grace.
