When you're asked to voice yourself in a game only so your digital visage can get can get pissed on and exploded by the player, you know your career might not be at its apex.
It isn't so much the acting in the satirical PC shooter Postal 2 that puts Gary on the list, as much as it is the sad subtext behind it.
Now, there are a lot of stars out there that eventually become walking jokes. Some embrace it, some become angry and bitter. Coleman took the idea of embracing it to a higher level of low when he agreed to get paid to be in a game that openly mocks the idea of Gary Coleman even being alive, by having you kill him within minutes of meeting him.
He isn't a part of the story in any way and he has no impact on anything. He's just there, as Gary Coleman, and the game is clearly programmed with the foregone conclusion that upon recognizing the man, any of us would
1) piss on him ...
... and 2) try to take his life.
We happen to think the game has over-estimated the amount of murderous animosity the public holds against Gary, but upon hearing the concept of the game, Coleman apparently nodded and said, "Yes, that sounds about right." Might need to work on the self-esteem there, Gary.
