Speaking as someone that has made mid-6 figures working on reality television:
you would not believe how cheesy the videos are.
All of 'em. Fer real. I've probably watched more reality TV audition videos than everyone here combined. More than everyone here and everyone they know combined. And you're rawkin'. That said,
Again, speaking as someone that has made mid-6 figures working on reality television, I generally advise everyone I know to stay the hell away from reality television. Competition reality's a little different, though. If you're really into it, throw down, baller. That's some impressive shit. You're eminently cast-able in my opinion. I'd say you're squarely in the wheelhouse of Naked & Afraid, Amazing Race, Survivor and Wipeout as well. They will edit you as the cocky nerd that nobody gets along with but is driven by altruism. It's a super-easy paradigm, super-necessary to every build and too much work to try anything else. If you have any tragedy whatsoever they pickaxe that shit out of your past like it's pure unobtanium; there will be an hour and a half of awkward questions from a story producer about Vladimir Vladimirov, as well as your mother, your father, lost loves, dead cats, whatever. They will then make a story assistant dig through Lexis Nexus, your photo album (you'll give it up - it'll be part of the contract), Google, anything they can find for still images. They will then layer some shit sad string ensemble over the top of it, steal shots of you talking about something genuinely sad (but off-topic) and attempt to build a narrative about how you're really only doing this to win approval from your dead mentor, the father figure your own couldn't provide.
If you can put up with that, kick ass and take names. If you can't, know it's coming. Because that's how we roll.
