His time on that Sci Fi original series had been well worth it, even though the pay was miniscule. Firearms training for actors can be cursory or intensive, and theirs had been intensive. Plus, he’d learned some actual science: how to make explosives from household items, how to distill drinking water, stuff like that. Stuff that turns out to be very useful come the zombie apocalypse.
The weird thing is, the show he’d been on had nothing to do with zombies: it was a gritty post-nuclear drama kind of deal. But after all, one apocalypse is just like any other.
