The box office is welcoming back Robert Pattinson — a lot of him. Pattinson stars in “Mickey 17,” an R-rated sci-fi movie from “Parasite” director Bong Joon Ho, where he plays multiple clones of the same person who dies repeatedly.

Robert Pattinson plays multiples in Mickey 17, but the main character and Mickey 18 are very different from each other. Here's the reason why.

Bong’s Mickey 17, adapted from Ashton Edward’s 2022 science-fiction novel Mickey7, is based on a terrific premise: It’s 2054 and hapless Earthling Mickey Barnes, played by Robert Pattinson, is so desperate to escape the repercussions of a bad debt that he signs on to be part of a group of eager citizens headed to a new and ostensibly better planet known as Niflheim.
