O diretor de Moon, Duncan Jones, falou sobre isso em uma série de entrevistas e comentários do diretor. Em suma, os clones são esperados para começar a quebrar em torno da marca de três anos. O que não está claro é se este é um comportamento projetado ou simplesmente um resquício do processo usado para cloná-los, mas a clara implicação é que ele é totalmente deliberado por parte de EvilCorp .
O que quer que esteja causando o colapso, não se deve à radiação na Lua, já que isso também o afetaria na Terra
The small canister that Sam 2 carries under his arm as he prepares for
his escape is meant to contain Helium 3, the resource being mined on
the moon, and valued at roughly $15 million. “The idea was that when
Sam got back to Earth he may only have three years to go but he’ll be
three years with a lot of cash.”
31 Things We Learned from Duncan Jones’ Moon Commentary
Sam tem um período de três anos " tempo de vida "
DUNCAN JONES: That was an opportunity to give Sam a physical prop to explain his degeneration as a character. The idea is that he has
this three-year lifespan and he starts to break down; the molar was a
way to show that. We were talking about wanting to avoid exposition.
There was a case of I could have either done that with a dialogue
scene between the Sams, or I could just show him losing a tooth. That
was the way we tried to get around those exposition moments.

Evidentemente, a chave era que a motivação de Sam (sua esposa e família) começaria a diminuir drasticamente se sua tarefa durasse mais de três anos.
In my mind, he was a test pilot who became an astronaut but gradually
he became a kind of miner; a working class guy. It wasn’t as specific
as you’d think but it left room for your imagination. We did talk
about how long he hadn’t seen his wife… I thought it was that he
thought he was going to [the moon] for only two months or six months
and it became three years. I thought, 'Why would anybody go up there
for three years? That’s crazy,’ but Duncan said he knew it was three
years and that’s when it became about the money..”
Jones also talked about Bell’s back story, saying, “His relationship
with his wife was a driving factor to why he took this job at the
beginning… Yes, he was going to go up there to get the money to buy a
house.”
Moon Interview: Director Duncan Jones and Star Sam Rockwell!
Fora do universo, o tempo de vida de Sam (e a duração do contrato) refletem as experiências de vida do próprio diretor.
Duncan Jones: Absolutely. Yeah, I’m gonna start off with a fairly pat
joke, you’ll have to forgive me. It’s no coincidence that Sam’s
contract is three years cause that’s how long I spent in Vanderbilt at
graduate school. That is seriously where I got the idea. ' Cause I was
very isolated there. I was working in graduate school, I was staying
in a flat on my own, I had broken up with my girlfriend, and then I
felt incredibly alienated. So that was a good inspiration to how Sam
was feeling.
