10 Tiny Movie Details That Give Away Character Secrets

1. Sam's Shirt Hints At Him Being A Clone - Moon

The terrific Sam Rockwell-starring sci-fi drama Moon follows Sam Bell (Sam Rockwell), a man who begins to mentally and physically unravel as he reaches the end of a three-year mining stint on the far side of the Moon.

It's eventually revealed that Sam is, in fact, one of hundreds of identical clones of the original Sam Bell, and his frayed sanity is a result of each clone's in-built, three-year lifespan.

Basically, Lunar Industries awakens a new clone when the previous one is "retired" - that is, incinerated - as is cleverly foreshadowed in the film's opening title sequence, where "Sam Prime" is wearing a shirt reading, "Wake me when it's quitting time."

The relevance this statement has to Sam's true nature speaks for itself, even if at this point in the movie it seems like nothing more than a goofy throwaway slogan.
