10 Mind-Bending Thrillers That Will Melt Your Brain

7. Trance

Danny Boyle is no stranger to psychological thrillers as he proves in Trance, which depicts art auctioneer Simon (James McAvoy) becoming embroiled in the theft of a painting at the hands of Franck (Vincent Cassell). Simon ends up suffering amnesia after a blow to the head, and can no longer remember where he helped stash the painting, so Franck enlists hypnotherapist Elizabeth Lamb (Rosario Dawson) to help him out.

However, Elizabeth begins engaging in a sexual relationship with both Simon and Franck, before revealing that Simon is her former abusive lover who failed to kick a gambling addiction, hence him getting involved in the present theft. Once Simon realises this, he tells Elizabeth - who now knows the location of the painting - run away with it, but she returns with a truck and kills Simon.

We then learn that all along, Elizabeth hypnotised Simon to go back to gambling, which would lead him to his present fate, and she then offers Franck the choice of forgetting everything she told him by clicking on the "Trance" app on an iPad she sent him. Franck's decision is left ambiguous.
