So, there is a new Australian movie called 'The Subjects' where 8 ppl are locked in a room and take a pill and get superpowers.

I saw an illegal upload on YouTube and watched part of it - there's a scene where one character attempts to teleport and accidentally ends up also teleporting slightly backwards in time, to create a weird effect where there's multiple versions of her in a room at once. There are other effects too.
Pretty interesting as transformation movies go.
